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

Fred Drake53912162006-07-29 13:22:49 +000058What's New in Python 2.5 beta 3?
59================================
Neal Norwitza1f10902006-07-12 07:28:29 +000060
Anthony Baxter5d32a9f2006-08-02 07:43:09 +000061*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +000062
63Core and builtins
64-----------------
65
Neal Norwitzc5e060d2006-08-02 06:14:22 +000066- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t, it previously
67 returned a long (see PEP 353).
68
Neal Norwitzf71ec5a2006-07-30 06:57:04 +000069- Bug #1515471: string.replace() accepts character buffers again.
70
Neal Norwitz07aadb12006-07-30 06:55:48 +000071- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
72 This provides the proper warning for struct.pack().
73 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
74
Neal Norwitz0d62a062006-07-30 06:53:31 +000075- Patch #1531113: Fix augmented assignment with yield expressions.
76 Also fix a SystemError when trying to assign to yield expressions.
77
Phillip J. Ebyf7575d02006-07-28 21:12:07 +000078- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
79 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
80 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
81 excessive filesystem operations during imports.
82
Tim Petersbc24eee2006-07-27 01:14:53 +000083- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
84 operations on signed longs that are formally undefined by C.
85 Unfortunately, at least one compiler now cares about that, so complicated
86 the code to make that compiler happy again.
87
Martin v. Löwis982e9fe2006-07-24 12:54:17 +000088- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
89
Martin v. Löwisd22968a2006-07-24 11:54:53 +000090- Patch #1232023: Stop including current directory in search
91 path on Windows.
92
Neal Norwitze1fdb322006-07-21 05:32:28 +000093- Fix some potential crashes found with failmalloc.
94
Neal Norwitze7563102006-07-17 01:00:16 +000095- Fix warnings reported by Klocwork's static analysis tool.
96
Neal Norwitz84be93b2006-07-16 01:50:38 +000097- Bug #1512814, Fix incorrect lineno's when code within a function
98 had more than 255 blank lines.
99
Georg Brandl9dceedb2006-07-12 15:31:17 +0000100- Patch #1521179: Python now accepts the standard options ``--help`` and
101 ``--version`` as well as ``/?`` on Windows.
102
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000103- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000104 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000105 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000106
Tim Peters112aad32006-07-19 00:03:19 +0000107- Bug #1524317: Compiling Python ``--without-threads`` failed.
108 The Python core compiles again then, and, in a build without threads, the
109 new ``sys._current_frames()`` returns a dictionary with one entry,
110 mapping the faux "thread id" 0 to the current frame.
111
Ronald Oussoren3075e162006-07-25 20:28:55 +0000112- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000113
Ronald Oussoren3075e162006-07-25 20:28:55 +0000114
Neal Norwitza1f10902006-07-12 07:28:29 +0000115Library
116-------
117
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000118- Correction of patch #1455898: In the mbcs decoder, set final=False
119 for stream decoder, but final=True for the decode function.
120
Georg Brandl07fec3a2006-08-01 18:49:24 +0000121- os.urandom no longer masks unrelated exceptions like SystemExit or
122 KeyboardInterrupt.
123
Martin v. Löwis4e678382006-07-30 13:00:31 +0000124- Bug #1525866: Don't copy directory stat times in
125 shutil.copytree on Windows
126
Georg Brandle34ac7c2006-07-30 11:07:23 +0000127- Bug #1002398: The documentation for os.path.sameopenfile now correctly
128 refers to file descriptors, not file objects.
129
Fred Drakefbdeaad2006-07-29 16:56:15 +0000130- Rename of the xml package to xmlcore, and the import hackery done to
131 make it appear at both names, has been removed. Bug #1511497,
132 #1513611, and probably others.
133
Georg Brandledd9b0d2006-07-29 09:33:26 +0000134- Bug #1441397: The compiler module now recognizes module and function
135 docstrings correctly as it did in Python 2.4.
136
Tim Peters6f681472006-07-27 23:44:37 +0000137- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
138 lost that tests are sorted by name before being run. This rarely
139 matters for well-written tests, but can create baffling symptoms if
140 side effects from one test to the next affect outcomes. ``DocTestFinder``
141 has been changed to sort the list of tests it returns.
142
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000143- The distutils version has been changed to 2.5.0, and are now kept
144 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000145
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000146- Bug #978833: Really close underlying socket in _socketobject.close.
147
Georg Brandl0619a322006-07-26 07:40:17 +0000148- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
149 with title().
150
Georg Brandlcf0c1722006-07-26 07:23:32 +0000151- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
152 to recursive calls and call it with the failing package name.
153
Martin v. Löwis0b483032006-07-25 09:53:12 +0000154- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
155
Georg Brandlc13c34c2006-07-24 14:09:56 +0000156- Patch #1515343: Fix printing of deprecated string exceptions with a
157 value in the traceback module.
158
Greg Ward48fae7a2006-07-23 16:05:51 +0000159- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
160
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000161- Patch #1524429: Use repr() instead of backticks in Tkinter again.
162
Brett Cannoncaebe222006-07-18 04:41:36 +0000163- Bug #1520914: Change time.strftime() to accept a zero for any position in its
164 argument tuple. For arguments where zero is illegal, the value is forced to
165 the minimum value that is correct. This is to support an undocumented but
166 common way people used to fill in inconsequential information in the time
167 tuple pre-2.4.
168
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000169- Patch #1220874: Update the binhex module for Mach-O.
170
Barry Warsawb110bad2006-07-21 14:51:07 +0000171- The email package has improved RFC 2231 support, specifically for
172 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
173 (name*0=<blah>) parameter continuations. This may change the types of
174 values returned from email.message.Message.get_param() and friends.
175 Specifically in some cases where non-encoded continuations were used,
176 get_param() used to return a 3-tuple of (None, None, string) whereas now it
177 will just return the string (since non-encoded continuations don't have
178 charset and language parts).
179
180 Also, whereas % values were decoded in all parameter continuations, they are
181 now only decoded in encoded parameter parts.
182
Ronald Oussoren3075e162006-07-25 20:28:55 +0000183- Bug #1517990: IDLE keybindings on MacOS X now work correctly
184
185- Bug #1517996: IDLE now longer shows the default Tk menu when a
186 path browser, class browser or debugger is the frontmost window on MacOS X
187
Barry Warsaw00decd72006-07-27 23:43:15 +0000188- Patch #1520294: Support for getset and member descriptors in types.py,
189 inspect.py, and pydoc.py. Specifically, this allows for querying the type
190 of an object against these built-in types and more importantly, for getting
191 their docstrings printed in the interactive interpreter's help() function.

195-----------------
196
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000197- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
198 a socket operation on a socket with a timeout, the exception will be
199 caught correctly. Previously, the exception was not caught.
200
Thomas Heller1393d6a2006-07-28 21:43:20 +0000201- Patch #1529514: The _ctypes extension is now compiled on more
202 openbsd target platforms.
203
Tim Peters9cab5932006-07-28 00:30:00 +0000204- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
205 a memory leak, affecting pickles and deep copies.
206
Tim Petersbc24eee2006-07-27 01:14:53 +0000207- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000208 Paul Eggert.
209
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000210- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
211
Thomas Hellerce049a02006-07-14 17:51:14 +0000212- Patch #1521817: Index range checking on ctypes arrays containing
213 exactly one element enabled again. This allows iterating over these
214 arrays, without the need to check the array size before.
215
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000216- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000217 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000218 /dev/null in certain cases; this is now fixed.
219
Thomas Heller47d7a062006-07-12 08:43:47 +0000220- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
221 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000222
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000223- Because of a misspelled preprocessor symbol, ctypes was always
224 compiled without thread support; this is now fixed.
225
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000226- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
227 methods now allow their database parameter to be None as the
228 sleepycat API allows.
229
Matt Flemingec926502006-07-28 11:27:27 +0000230- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
231 bluetooth API compared with Linux and FreeBSD.
232
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000233Tests
234-----
235
236- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
237 how long the test file should take to play. Now accepts taking 2.93 secs
238 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
239
Georg Brandl4793aa32006-07-28 18:31:39 +0000240- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
241 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
242 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000249Mac
250---
251
252- PythonLauncher now works correctly when the path to the script contains
253 characters that are treated specially by the shell (such as quotes).
254
255- Bug #1527397: PythonLauncher now launches scripts with the working directory
256 set to the directory that contains the script instead of the user home
257 directory. That latter was an implementation accident and not what users
258 expect.

Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000269- Bug #1441486: The literal representation of -(sys.maxint - 1)
270 again evaluates to a int object, not a long.
271
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000272- Bug #1501934: The scope of global variables that are locally assigned
273 using augmented assignment is now correctly determined.
274
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000275- Bug #927248: Recursive method-wrapper objects can now safely
276 be released.
277
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000278- Bug #1417699: Reject locale-specific decimal point in float()
279 and atof().
280
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000281- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
282 omit a default "error" argument for NULL pointer. This allows
283 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000284
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000285- Bug #1519018: 'as' is now validated properly in import statements.
286
Neal Norwitz28746ab2006-07-09 22:14:42 +0000287- On 64 bit systems, int literals that use less than 64 bits are
288 now ints rather than longs.
289
Neal Norwitzed657552006-07-10 00:04:44 +0000290- Bug #1512814, Fix incorrect lineno's when code at module scope
291 started after line 256.
292
Tim Peters32a83612006-07-10 21:08:24 +0000293- New function ``sys._current_frames()`` returns a dict mapping thread
294 id to topmost thread stack frame. This is for expert use, and is
295 especially useful for debugging application deadlocks. The functionality
296 was previously available in Fazal Majid's ``threadframe`` extension
297 module, but it wasn't possible to do this in a wholly threadsafe way from
298 an extension.

315
Thomas Woutersadd19112006-07-05 11:03:49 +0000316- string.Template() now correctly handles tuple-values. Previously,
317 multi-value tuples would raise an exception and single-value tuples would
318 be treated as the value they contain, instead.
319
Martin v. Löwisede77f52006-07-03 13:01:35 +0000320- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

333 is created.
334
Martin v. Löwis7596e832006-07-01 15:33:37 +0000335- Bug #1513223: .close() of a _socketobj now releases the underlying
336 socket again, which then gets closed as it becomes unreferenced.
337

341- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
342 sgmllib ('[' and ']' were not accepted).
343
Georg Brandl1be63af2006-06-28 20:23:25 +0000344- Fix a bug in the turtle module's end_fill function.
345
Brett Cannon53ab5b72006-06-22 16:49:14 +0000346- Bug #1510580: The 'warnings' module improperly required that a Warning
347 category be either a types.ClassType and a subclass of Warning. The proper
348 check is just that it is a subclass with Warning as the documentation states.
349
Georg Brandlad29e632006-06-21 17:45:17 +0000350- The compiler module now correctly compiles the new try-except-finally
351 statement (bug #1509132).
352
Neal Norwitz60373cd2006-06-22 06:30:50 +0000353- The wsgiref package is now installed properly on Unix.
354
Vinay Sajip28e57612006-07-01 10:45:20 +0000355- A bug was fixed in logging.config.fileConfig() which caused a crash on
356 shutdown when fileConfig() was called multiple times.
357
Gerhard Häring762fbd32006-07-02 17:48:30 +0000358- The sqlite3 module did cut off data from the SQLite database at the first
359 null character before sending it to a custom converter. This has been fixed
360 now.

363-----------------
364
Tim Peters112aad32006-07-19 00:03:19 +0000365- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
366 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
367 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000368
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000369- Assigning None to pointer type fields in ctypes structures possible
370 overwrote the wrong fields, this is fixed now.
371
372- Fixed a segfault in _ctypes when ctypes.wintypes were imported
373 on non-Windows platforms.
374
375- Bug #1518190: The ctypes.c_void_p constructor now accepts any
376 integer or long, without range checking.
377
378- Patch #1517790: It is now possible to use custom objects in the ctypes
379 foreign function argtypes sequence as long as they provide a from_param
380 method, no longer is it required that the object is a ctypes type.
381
382- The '_ctypes' extension module now works when Python is configured
383 with the --without-threads option.
384
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000385- Bug #1513646: os.access on Windows now correctly determines write
386 access, again.
387
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000388- Bug #1512695: cPickle.loads could crash if it was interrupted with
389 a KeyboardInterrupt.
390
Neal Norwitza12aa882006-07-06 06:45:08 +0000391- Bug #1296433: parsing XML with a non-default encoding and
392 a CharacterDataHandler could crash the interpreter in pyexpat.
393
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000394- Patch #1516912: improve Modules support for OpenVMS.

400
Tim Peters32a83612006-07-10 21:08:24 +0000401- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000402 Previously, the slight difference could cause compilation errors of the
403 'zlib' module on systems with more than one version of zlib.
404
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000405- The MSI compileall step was fixed to also support a TARGETDIR
406 with spaces in it.
407

Anthony Baxter51bcb682006-04-05 14:51:42 +0000434
435Core and builtins
436-----------------
437
Georg Brandla56b9152006-06-19 06:35:54 +0000438- Patch #1507676: Error messages returned by invalid abstract object operations
439 (such as iterating over an integer) have been improved and now include the
440 type of the offending object to help with debugging.
441
Brett Cannonea3912b2006-06-13 21:46:41 +0000442- Bug #992017: A classic class that defined a __coerce__() method that returned
443 its arguments swapped would infinitely recurse and segfault the interpreter.
444
Neal Norwitz909eb122006-06-12 02:13:21 +0000445- Fix the socket tests so they can be run concurrently.
446
Neal Norwitzb9845e72006-06-12 02:11:18 +0000447- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000448 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000449
Brett Cannon22565aa2006-06-09 22:31:23 +0000450- Bug #532646: object.__call__() will continue looking for the __call__
451 attribute on objects until one without one is found. This leads to recursion
452 when you take a class and set its __call__ attribute to an instance of the
453 class. Originally fixed for classic classes, but this fix is for new-style.
454 Removes the infinite_rec_3 crasher.
455
Georg Brandl24250812006-06-09 18:45:48 +0000456- The string and unicode methods startswith() and endswith() now accept
457 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
458
Brett Cannonde3b0522006-06-08 17:00:45 +0000459- Buffer objects, at the C level, never used the char buffer
460 implementation even when the char buffer for the wrapped object was
461 explicitly requested (originally returned the read or write buffer).
462 Now a TypeError is raised if the char buffer is not present but is
463 requested.
464
Georg Brandlddbaa662006-06-04 21:56:52 +0000465- Patch #1346214: Statements like "if 0: suite" are now again optimized
466 away like they were in Python 2.4.
467
Georg Brandlb7c8f542006-05-27 12:30:25 +0000468- Builtin exceptions are now full-blown new-style classes instead of
469 instances pretending to be classes, which speeds up exception handling
470 by about 80% in comparison to 2.5a2.
471
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000472- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
473 Unicode 4.1.
474
Georg Brandlf4ef1162006-05-26 18:03:31 +0000475- Patch #921466: sys.path_importer_cache is now used to cache valid and
476 invalid file paths for the built-in import machinery which leads to
477 fewer open calls on startup.
478
Tim Peters696cf432006-05-24 21:10:40 +0000479- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
480 of-2 bases. The largest speedup is for inputs with about 1000 decimal
481 digits. Conversion from non-power-of-2 bases remains quadratic-time in
482 the number of input digits (it was and remains linear-time for bases
483 2, 4, 8, 16 and 32).
484
Tim Petersb713ec22006-05-23 18:45:30 +0000485- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
486 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
487 an integer close to ``sys.maxint``. This was repaired by patch
488 #1335972, which also gives a nice speedup.
489
Richard Jonescebbefc2006-05-23 18:28:17 +0000490- Patch #1337051: reduced size of frame objects.
491
492- PyErr_NewException now accepts a tuple of base classes as its
493 "base" parameter.
494
Richard Jones7c88dcc2006-05-23 10:37:38 +0000495- Patch #876206: function call speedup by retaining allocated frame
496 objects.
497
Georg Brandl7b90e162006-05-18 07:01:27 +0000498- Bug #1462152: file() now checks more thoroughly for invalid mode
499 strings and removes a possible "U" before passing the mode to the
500 C library function.
501
Neal Norwitz1004a532006-05-15 07:17:23 +0000502- Patch #1488312, Fix memory alignment problem on SPARC in unicode
503
Neal Norwitz373f0a72006-05-15 07:04:36 +0000504- Bug #1487966: Fix SystemError with conditional expression in assignment
505
Martin v. Löwis879768d2006-05-11 13:28:43 +0000506- WindowsError now has two error code attributes: errno, which carries
507 the error values from errno.h, and winerror, which carries the error
508 values from winerror.h. Previous versions put the winerror.h values
509 (from GetLastError()) into the errno attribute.
510
Martin v. Löwis77736712006-05-04 05:51:03 +0000511- Patch #1475845: Raise IndentationError for unexpected indent.
512
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000513- Patch #1479181: split open() and file() from being aliases for each other.
514
Tim Peters44bd9862006-06-01 13:49:23 +0000515- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
516 methods were always silently ignored by dictionaries when comparing keys.
517 They are now passed through (except when using the C API function
518 ``PyDict_GetItem()``, whose semantics did not change).
519
520- Bug #1456209: In some obscure cases it was possible for a class with a
521 custom ``__eq__()`` method to confuse dict internals when class instances
522 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
523 No, you don't have any code that did this ;-)

531
Brett Cannon6ee7d012006-06-08 16:23:04 +0000532- Change binascii.hexlify to accept a read-only buffer instead of only a char
533 buffer and actually follow its documentation.
534
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000535- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
536
Nick Coghlanc649ec52006-05-29 12:43:05 +0000537- Patch #1478788 (modified version): The functional extension module has
538 been renamed to _functools and a functools Python wrapper module added.
539 This provides a home for additional function related utilities that are
540 not specifically about functional programming. See PEP 309.
541
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000542- Patch #1493701: performance enhancements for struct module.

550 enabled builds on Windows and systems with Posix threads support.
551
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000552- On Win32, os.listdir now supports arbitrarily-long Unicode path names
553 (up to the system limit of 32K characters).
554
555- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
556 As a result, these functions now raise WindowsError instead of OSError.
557
Tim Peters7a822da2006-05-25 21:50:17 +0000558- ``time.clock()`` on Win64 should use the high-performance Windows
559 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
560 Windows platforms).
561
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000562- Calling Tk_Init twice is refused if the first call failed as that
563 may deadlock.
564
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000565- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
566 accept it without potentially using an uninitialized pointer.
567
568- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
569 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

581
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000582- bsddb: the bsddb.dbtables Modify method now raises the proper error and
583 aborts the db transaction safely when a modifier callback fails.
584 Fixes SF python patch/bug #1408584.
585
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000586- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000587 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000588 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
589 database calls that would previously deadlock. [SF python bug #775414]

619 double-byte encodings.
620
Tim Peters43898b42006-06-14 04:09:25 +0000621- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
622 guarantee that adjacent triples in the return list always describe
623 non-adjacent blocks. Previously, a pair of matching blocks could end
624 up being described by multiple adjacent triples that formed a partition

Greg Ward0e0c9f42006-06-11 16:24:11 +0000627- Bug #1498146: fix optparse to handle Unicode strings in option help,
628 description, and epilog.
629
Greg Wardd1c797e2006-06-11 14:42:41 +0000630- Bug #1366250: minor optparse documentation error.
631
Greg Ward7f547402006-06-11 00:40:49 +0000632- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
633 clarify docs.
634
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000635- The wsgiref package has been added to the standard library.
636
Nick Coghlan676725d2006-06-08 13:54:49 +0000637- The functions update_wrapper() and wraps() have been added to the functools
638 module. These make it easier to copy relevant metadata from the original
639 function when writing wrapper functions.
640
Tim Petersd6a9eef2006-06-05 01:48:21 +0000641- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
642 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000643
Martin v. Löwis3f767792006-06-04 19:36:28 +0000644- Patch #1359618: Speed up charmap encoder by using a trie structure
645 for lookup.
646
Tim Petersd609b1a2006-06-02 23:22:51 +0000647- The functions in the ``pprint`` module now sort dictionaries by key
648 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
649 if and only if its display required more than one line, although that
650 wasn't documented. The new behavior increases predictability; e.g.,
651 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
652
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000653- Patch #1497027: try HTTP digest auth before basic auth in urllib2
654 (thanks for J. J. Lee).
655
Georg Brandl2b330372006-05-28 20:23:12 +0000656- Patch #1496206: improve urllib2 handling of passwords with respect to
657 default HTTP and HTTPS ports.
658
George Yoshidaf3c65de2006-05-28 16:39:09 +0000659- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
660
Bob Ippolito7298f272006-05-23 18:43:47 +0000661- Patch #1281707: speed up gzip.readline.
662
Georg Brandlb89316f2006-05-17 15:51:16 +0000663- Patch #1180296: Two new functions were added to the locale module:
664 format_string() to get the effect of "format % items" but locale-aware,
665 and currency() to format a monetary number with currency sign.
666
Georg Brandle3a25832006-05-17 14:56:04 +0000667- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
668 and several features added, such as speed and geometry control.
669
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000670- Patch #1488881: add support for external file objects in bz2 compressed
671 tarfiles.
672
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000673- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
674 stdout arguments, making it possible to redirect input and output
675 for remote debugging.
676
677- Patch #1484695: Update the tarfile module to version 0.8. This fixes
678 a couple of issues, notably handling of long file names using the
679 GNU LONGNAME extension.
680
681- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
682 new flag when ``name`` is already the name of an option flag.
683
684- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
685 package.
686
687- Patch #1472854: make the rlcompleter.Completer class usable on non-
688 UNIX platforms.
689
690- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
691
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000692- Bug #1472827: correctly escape newlines and tabs in attribute values in
693 the saxutils.XMLGenerator class.

722
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000723What's New in Python 2.5 alpha 2?
724=================================
725
726*Release date: 27-APR-2006*
727
728Core and builtins
729-----------------
730
Thomas Heller1b046642006-04-18 18:51:06 +0000731- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
732 by converting these apis from macros into exported functions again:
733
734 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
735 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
736 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
737 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
738 PyRun_String Py_CompileString
739
Martin v. Löwis45294a92006-04-18 06:24:08 +0000740- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
741
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000742- All uses of PyStructSequence_InitType have been changed to initialize
743 the type objects only once, even if the interpreter is initialized
744 multiple times.
745
Neal Norwitz61546162006-04-14 05:20:28 +0000746- Bug #1454485, array.array('u') could crash the interpreter. This was
747 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
748 to unicode when it didn't make sense. 'u#' now requires a unicode string.
749
750- Py_UNICODE is unsigned. It was always documented as unsigned, but
751 due to a bug had a signed value in previous versions.
752
Tim Peters3a5e8b12006-04-11 01:44:07 +0000753- Patch #837242: ``id()`` of any Python object always gives a positive
754 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
755 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000756 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000757 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000758
Tim Peters3a5e8b12006-04-11 01:44:07 +0000759 def __hash__(self):
760 return id(self) # WRONG
761
762 because a hash result must be a (short) Python int but it was always
763 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000764 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000765 was always usable as a hash value before this patch. That's no longer
766 necessarily so.
767
768- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000769 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000770 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000771 #1454844)
772
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000773- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
774 involving generators that have paused outside of any ``try`` or ``with``
775 blocks. (In 2.5a1, a paused generator that was part of a reference
776 cycle could not be garbage collected, regardless of whether it was
777 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000779Extension Modules

783 is a macro.
784
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000785- Bug #1467952: os.listdir() now correctly raises an error if readdir()
786 fails with an error condition.
787
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000788- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
789
790- Bug #1117761: bsddb.*open() no longer raises an exception when using
791 the cachesize parameter.
792
793- Bug #1149413: bsddb.*open() no longer raises an exception when using
794 a temporary db (file=None) with the 'n' flag to truncate on open.
795
796- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
797 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000798
Armin Rigoa9017c32006-04-19 11:50:27 +0000799- Patch #1062014: AF_UNIX sockets under Linux have a special

803-------
804
Peter Astrand7d1d4362006-07-14 14:04:45 +0000805- Bug #1223937: subprocess.CalledProcessError reports the exit status
806 of the process using the returncode attribute, instead of
807 abusing errno.
808
Tim Peters711bf302006-04-25 03:31:36 +0000809- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
810 a doctest to be skipped (the code is not run, and the expected output
811 or exception is ignored).
812
Nick Coghlanda2268f2006-04-24 04:37:15 +0000813- Fixed contextlib.nested to cope with exceptions being raised and
814 caught inside exit handlers.
815
Greg Wardab05edc2006-04-23 03:47:58 +0000816- Updated optparse module to Optik 1.5.1 (allow numeric constants in
817 hex, octal, or binary; add ``append_const`` action; keep going if
818 gettext cannot be imported; added ``OptionParser.destroy()`` method;
819 added ``epilog`` for better help generation).
820
Tim Peters21fbd572006-04-21 21:18:10 +0000821- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
822 called from a thread spawned as a side effect of importing a module.
823
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000824- The pydoc module now supports documenting packages contained in
825 .zip or .egg files.
826
827- The pkgutil module now has several new utility functions, such
828 as ``walk_packages()`` to support working with packages that are either
829 in the filesystem or zip files.
830
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000831- The mailbox module can now modify and delete messages from
832 mailboxes, in addition to simply reading them. Thanks to Gregory
833 K. Johnson for writing the code, and to the 2005 Google Summer of
834 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000835
Tim Petersc7605f22006-04-17 21:12:33 +0000836- The ``__del__`` method of class ``local`` in module ``_threading_local``
837 returned before accomplishing any of its intended cleanup.
838
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000839- Patch #790710: Add breakpoint command lists in pdb.
840
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000841- Patch #1063914: Add Tkinter.Misc.clipboard_get().

844
Anthony Baxtere29002c2006-04-12 12:07:31 +0000845- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
846 Windows. Bug #1469163.
847
Phillip J. Eby47032112006-04-11 01:07:43 +0000848- The warnings, linecache, inspect, traceback, site, and doctest modules
849 were updated to work correctly with modules imported from zipfiles or
850 via other PEP 302 __loader__ objects.
851
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000852- Patch #1467770: Reduce usage of subprocess._active to processes which
853 the application hasn't waited on.
854

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000872- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
873 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000874 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000875 CXX from --with-cxx-main, see description in README.
876

887
Nick Coghlanda2268f2006-04-24 04:37:15 +0000888- test_contextlib now checks contextlib.nested can cope with exceptions
889 being raised and caught inside exit handlers.
890
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000891- test_cmd_line now checks operation of the -m and -c command switches
892
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000893- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
894 it separately and by hand. It also wasn't cleaning up its changes to
895 the current Decimal context.
896
Thomas Woutersabd08882006-04-26 15:53:30 +0000897- regrtest.py now has a -M option to run tests that test the new limits of
898 containers, on 64-bit architectures. Running these tests is only sensible
899 on 64-bit machines with more than two gigabytes of memory. The argument
900 passed is the maximum amount of memory for the tests to use.

928
Nick Coghlan43832302006-04-23 17:04:07 +0000929- PEP 338: -m command line switch now delegates to runpy.run_module
930 allowing it to support modules in packages and zipfiles
931
Martin v. Löwisc661b882006-04-20 04:54:23 +0000932- On Windows, .DLL is not an accepted file name extension for
933 extension modules anymore; extensions are only found if they
934 end in .PYD.
935
Martin v. Löwisea62d252006-04-03 10:56:49 +0000936- Bug #1421664: sys.stderr.encoding is now set to the same value as
937 sys.stdout.encoding.

Neal Norwitze98ccf62006-03-23 05:39:47 +0000948- Bug #1115379: Compiling a Unicode string with an encoding declaration
949 now gives a SyntaxError.

Georg Brandlabd1ff82006-03-18 07:59:59 +0000951- Previously, Python code had no easy way to access the contents of a
952 cell object. Now, a ``cell_contents`` attribute has been added
953 (closes patch #1170323).
954
Tim Peterscf79aac2006-03-16 01:14:46 +0000955- Patch #1123430: Python's small-object allocator now returns an arena to
956 the system ``free()`` when all memory within an arena becomes unused
957 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
958 freed. Some applications will see a drop in virtual memory size now,
959 especially long-running applications that, from time to time, temporarily
960 use a large number of small objects. Note that when Python returns an
961 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000962 platform C library will in turn return that memory to the operating system.
963 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000964 appears to be effective at least on Microsoft C and gcc-based systems.
965 Thanks to Evan Jones for hard work and patience.
966
Georg Brandl533ff6f2006-03-08 18:09:27 +0000967- Patch #1434038: property() now uses the getter's docstring if there is
968 no "doc" argument given. This makes it possible to legitimately use
969 property() as a decorator to produce a read-only property.
970
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000971- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
972 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
973 of requiring an int or long in slicing and a few other contexts, enabling
974 other objects (e.g. Numeric Python's integers) to be used as slice indices.
975
Neal Norwitz995acdf2006-03-07 05:01:00 +0000976- Fixed various bugs reported by Coverity's Prevent tool.
977
Brett Cannonbf364092006-03-01 04:25:17 +0000978- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
979 new exception base class, BaseException, which has a new message attribute.
980 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
981 Raising a string exception now raises a DeprecationWarning.
982
Thomas Woutersfb609f42006-02-28 16:37:25 +0000983- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
984 explicitly relative, using 'from .module import name' to mean 'from the same
985 package as this module is in. Imports without dots still default to the
986 old relative-then-absolute, unless 'from __future__ import
987 absolute_import' is used.
988
Brett Cannona7446e32006-02-27 23:39:10 +0000989- Properly check if 'warnings' raises an exception (usually when a filter set
990 to "error" is triggered) when raising a warning for raising string
991 exceptions.
992
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000993- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000994 The name was removed from Include/code.h.
995
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000996- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000997
Guido van Rossum1968ad32006-02-25 22:38:04 +0000998- Patch 1433928:
999 - The copy module now "copies" function objects (as atomic objects).
1000 - dict.__getitem__ now looks for a __missing__ hook before raising
1001 KeyError.
1002
Tim Peters84ef21c2006-02-28 20:39:06 +00001003- PEP 343: with statement implemented. Needs ``from __future__ import
1004 with_statement``. Use of 'with' as a variable will generate a warning.
1005 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001006 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001007 The following objects have __context__ methods:
1008 - The built-in file type.
1009 - The thread.LockType type.
1010 - The following types defined by the threading module:
1011 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1012 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001013
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001014- Fix the encodings package codec search function to only search
1015 inside its own package. Fixes problem reported in patch #1433198.
1016
1017 Note: Codec packages should implement and register their own
1018 codec search function. PEP 100 has the details.
1019
Tim Peters9ea89d22006-06-04 03:26:02 +00001020- PEP 353: Using ``Py_ssize_t`` as the index type.
1021
1022- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1023 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1024 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1025 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1026 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001027
Neal Norwitzfc76d632006-01-10 06:03:13 +00001028- Patch #1400181, fix unicode string formatting to not use the locale.
1029 This is how string objects work. u'%f' could use , instead of .
1030 for the decimal point. Now both strings and unicode always use periods.
1031
Neal Norwitz671b9e32006-01-09 07:07:12 +00001032- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1033 configure would break checking curses.h.
1034
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001035- Bug #959576: The pwd module is now builtin. This allows Python to be
1036 built on UNIX platforms without $HOME set.
1037
Neal Norwitzc10978f2005-12-19 06:07:16 +00001038- Bug #1072182, fix some potential problems if characters are signed.
1039
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001040- Bug #889500, fix line number on SyntaxWarning for global declarations.
1041
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001042- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1043
Neal Norwitze7214a12005-12-18 05:03:17 +00001044- Support for converting hex strings to floats no longer works.
1045 This was not portable. float('0x3') now raises a ValueError.
1046
Barry Warsaw2a38a862005-12-18 01:27:35 +00001047- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001048 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001049 is now displayed in interactive prompt banner.
1050
Georg Brandlfa166682005-12-17 21:45:17 +00001051- Implementation of PEP 341 - Unification of try/except and try/finally.
1052 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001053 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001054
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001055- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1056 now encodes backslash correctly.
1057
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001058- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1059
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001060- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001061 and long longs.
1062
Neal Norwitz67715f02005-11-09 06:59:35 +00001063- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001064 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001065 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001066
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001067- Replaced most Unicode charmap codecs with new ones using the
1068 new Unicode translate string feature in the builtin charmap
1069 codec; the codecs were created from the mapping tables available
1070 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1071 encodings now include a mapping for the Apple logo)
1072
Tim Peterse3547fd2005-12-16 23:13:57 +00001073- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001074
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001075- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001076
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001077- A new AST parser implementation was completed. The abstract
1078 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001079 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001080
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001081- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001082 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1083
Neal Norwitz708e51a2005-10-03 04:48:15 +00001084- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1085
Neal Norwitz11bd1192005-10-03 00:54:56 +00001086- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1087 Provide a warning when a directory is passed on the command line.
1088
Neal Norwitz40d37812005-10-02 01:48:49 +00001089- Fix segfault with invalid coding.
1090
1091- SF bug #772896: unknown encoding results in MemoryError.
1092
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001093- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001094 supported a __len__() method which evaluated to False when the iterator
1095 was empty.
1096
Guido van Rossum630db602005-09-20 18:49:54 +00001097- On 64-bit platforms, when __len__() returns a value that cannot be
1098 represented as a C int, raise OverflowError.
1099
Skip Montanarof8948ca2005-09-19 03:54:46 +00001100- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001101 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001102
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001103- SF bug #893549: parsing keyword arguments was broken with a few format
1104 codes.
1105
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001106- Changes donated by Elemental Security to make it work on AIX 5.3
1107 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1108 bug #105470: test_pwd fails on 64bit system (Opteron).
1109
Guido van Rossum539c6622005-09-14 17:49:54 +00001110- Changes donated by Elemental Security to make it work on HP-UX 11 on
1111 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1112
Georg Brandl4550b8d2005-08-26 06:43:52 +00001113- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001114 (fixes bug #1119418).
1115
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001116- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1117
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001118- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1119 exceptions that cause a function to exit.
1120
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001121- The implementation of set() and frozenset() was revised to use its
1122 own internal data structure. Memory consumption is reduced by 1/3
1123 and there are modest speed-ups as well. The API is unchanged.
1124
Tim Petersde7990b2005-07-17 23:45:23 +00001125- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1126
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001127- SF bug #1229429: PyObject_CallMethod failed to decrement some
1128 reference counts in some error exit cases.
1129
Tim Petersecc6e6a2005-07-10 22:30:55 +00001130- SF bug #1185883: Python's small-object memory allocator took over
1131 a block managed by the platform C library whenever a realloc specified
1132 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001133 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001134 portable way to copy data from the C-managed block into Python's
1135 small-object space without risking a memory fault. Python's small-object
1136 realloc now leaves such blocks under the control of the platform C
1137 realloc.
1138
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001139- SF bug #1232517: An overflow error was not detected properly when
1140 attempting to convert a large float to an int in os.utime().
1141
Raymond Hettinger3296e692005-06-29 23:29:56 +00001142- SF bug #1224347: hex longs now print with lowercase letters just
1143 like their int counterparts.
1144
Michael W. Hudson188d4362005-06-20 16:52:57 +00001145- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1146 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1147 interpreter states; back out that fix and do a better job (see
1148 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1149 for a longer write-up of the problem).
1150
Michael W. Hudsondf888462005-06-03 14:41:55 +00001151- SF patch #1180995: marshal now uses a binary format by default when
1152 serializing floats.
1153
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001154- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1155 the routines that promise to produce IEEE 754 binary representations
1156 of floats now simply copy bytes around.
1157
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001158- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1159 278.
1160
Brett Cannonc3647ac2005-04-26 03:45:26 +00001161- patch #1109424: int, long, float, complex, and unicode now check for the
1162 proper magic slot for type conversions when subclassed. Previously the
1163 magic slot was ignored during conversion. Semantics now match the way
1164 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001165 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001166 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001167 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001168
Barry Warsawc8d907c2005-04-19 23:43:40 +00001169- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1170 NULL, now raise an AttributeError when attempting to set or delete the
1171 attribute. Previously a TypeError was raised, but this was inconsistent
1172 with the equivalent pure-Python implementation.
1173
Michael W. Hudson774479c2005-04-18 08:46:17 +00001174- It is now safe to call PyGILState_Release() before
1175 PyEval_InitThreads() (note that if there is reason to believe there
1176 are multiple threads around you still must call PyEval_InitThreads()
1177 before using the Python API; this fix is for extension modules that
1178 have no way of knowing if Python is multi-threaded yet).
1179
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001180- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1181 disabled caused a crash.
1182
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001183- Bug #1165306: instancemethod_new allowed the creation of a method
1184 with im_class == im_self == NULL, which caused a crash when called.
1185
Tim Petersecc6e6a2005-07-10 22:30:55 +00001186- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001187 fixes the crash seen in bug #1165761
1188
Raymond Hettinger96229b12005-03-11 06:49:40 +00001189- Added two new builtins, any() and all().
1190
Brett Cannon409d8f22005-03-05 06:47:57 +00001191- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001192 (e.g., ``class C(): pass`` is no longer a syntax error).
1193 Patch #1176012 added support to the 'parser' module and 'compiler' package
1194 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001195
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001196- Patch #1115086: Support PY_LONGLONG in structmember.
1197
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001198- Bug #1155938: new style classes did not check that __init__() was
1199 returning None.
1200
Tim Petersecc6e6a2005-07-10 22:30:55 +00001201- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001202 ('\') with a specific error message.
1203
Martin v. Löwisff232d72005-03-03 09:24:38 +00001204- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1205
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001206- Bug #1124295: the __name__ attribute of file objects was
1207 inadvertently made inaccessible in restricted mode.
1208
Tim Petersecc6e6a2005-07-10 22:30:55 +00001209- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001210 an ferror() call.
1211
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001212- min() and max() now support key= arguments with the same meaning as in

Jeremy Hyltonab630502005-02-04 18:44:06 +00001223- The parser did not complain about future statements in illegal
1224 positions. It once again reports a syntax error if a future
1225 statement occurs after anything other than a doc string.
1226
Neil Schemenauercf52c072005-08-12 17:34:58 +00001227- Change the %s format specifier for str objects so that it returns a
1228 unicode instance if the argument is not an instance of basestring and
1229 calling __str__ on the argument returns a unicode instance.
1230
Tim Petersf4e69282006-02-27 17:15:31 +00001231- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1232 current thread state when the auto-GIL-state machinery knows about
1233 it (since the thread state is being deleted, continuing to remember it
1234 can't help, but can hurt if another thread happens to get created with
1235 the same thread id).

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001427- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1428 been renamed to have only a single underscore prefix. This was done to
1429 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001430
Nick Coghlan43832302006-04-23 17:04:07 +00001431- PEP 338: new module runpy defines a run_module function to support
1432 executing modules which provide access to source code or a code object
1433 via the PEP 302 import mechanisms.
1434
Anthony Baxter93f5b932006-04-03 08:05:07 +00001435- The email module's parsedate_tz function now sets the daylight savings

1443 in attribute values.
1444
Anthony Baxterc51ee692006-04-01 00:57:31 +00001445- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001446 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001447 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001448 module will not be built.
1449
Tim Petersc17976e2006-04-01 00:26:53 +00001450- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1451 aren't officially supported here, and trying to use them will probably
1452 raise an exception some day. But dicts have been allowed, and "mostly
1453 worked", so support for them won't go away without warning.
1454
Georg Brandl338ef7d2006-03-31 18:42:16 +00001455- Bug #1445068: getpass.getpass() can now be given an explicit stream
1456 argument to specify where to write the prompt.
1457
Georg Brandl22ec80b2006-03-31 18:25:44 +00001458- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1473
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001474- email 4.0 package now integrated. This is largely the same as the email 3.0
1475 package that was included in Python 2.3, except that PEP 8 module names are
1476 now used (e.g. mail.message instead of email.Message). The MIME classes
1477 have been moved to a subpackage (e.g. email.mime.text instead of
1478 email.MIMEText). The old names are still supported for now. Several
1479 deprecated Message methods have been removed and lots of bugs have been

1483 (a subclass of tuple) that provides incremental decoders and encoders
1484 (a way to use stateful codecs without the stream API). Python functions

1570
1571 "The consensus of researchers in this area (at least as
1572 expressed at the NIST Hash Function Workshop 10/31/05),
1573 is that SHA-256 is a good choice for the time being, but
1574 that research should continue, and other alternatives may
1575 arise from this research. The larger SHA's also seem OK."

Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001741 flags on the HTTP listening socket.
1742
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001743- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1744 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1745
Fred Drakefbdeaad2006-07-29 16:56:15 +00001746- Patches #893642, #1039083: add allow_none, encoding arguments to
1747 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.

Martin v. Löwis1d11de62005-01-29 13:29:23 +00001749- Bug #1110478: Revert os.environ.update to do putenv again.
1750
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001751- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1752
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001753- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1754
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001755- Enhancements to the csv module:
1756
1757 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001758 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001759 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001760 + Dialect parameter parsing has been re-implemented to improve error
1761 reporting.
1762 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1763 dictates.
1764 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001765 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001766 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001767 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1768 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001769 + reader now allows \r characters to be quoted (previously it only allowed
1770 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001771 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001772 + Dialect classes passed to the module are no longer instantiated by
1773 the module before being parsed (the former validation scheme required
1774 this, but the mechanism was unreliable).
1775 + The dialect registry now contains instances of the internal
1776 C-coded dialect type, rather than references to python objects.
1777 + the internal c-coded dialect type is now immutable.
1778 + register_dialect now accepts the same keyword dialect specifications
1779 as the reader and writer, allowing the user to register dialects
1780 without first creating a dialect class.
1781 + a configurable limit to the size of parsed fields has been added -
1782 previously, an unmatched quote character could result in the entire
1783 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001784 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001785 the parser field size limit (returning the former limit). The initial
1786 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001787 + A line_num attribute has been added to the reader object, which tracks
1788 the number of lines read from the source iterator. This is not
1789 the same as the number of records returned, as records can span
1790 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001791 + reader and writer objects were not being registered with the cyclic-GC.
1792 This has been fixed.
1793
Brett Cannone6539c42005-01-08 02:43:53 +00001794- _DummyThread objects in the threading module now delete self.__block that is
1795 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1796 lock primitives tend to be limited in number and thus should not be wasted on
1797 a _DummyThread object. Fixes bug #1089632.
1798
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001799- The imghdr module now detects Exif files.
1800
Raymond Hettinger6065d322004-12-20 23:51:53 +00001801- StringIO.truncate() now correctly adjusts the size attribute.
1802 (Bug #951915).
1803
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001804- locale.py now uses an updated locale alias table (built using
1805 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1806 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001807 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001808
Raymond Hettinger3557f422004-12-07 12:02:02 +00001809- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1810
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001811- the pickle module no longer accepts the deprecated None option in the
1812 args tuple returned by __reduce__().
1813
Brett Cannon84667c02004-12-07 03:25:18 +00001814- optparse now optionally imports gettext. This allows its use in setup.py.
1815
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001816- the pickle module no longer uses the deprecated bin parameter.
1817
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001818- the shelve module no longer uses the deprecated binary parameter.
1819
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001820- the pstats module no longer uses the deprecated ignore() method.
1821
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001822- the filecmp module no longer uses the deprecated use_statcache argument.
1823
Raymond Hettinger664347b2004-12-04 21:21:53 +00001824- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1825 extended or overridden by subclasses. Formerly, the subclassed method would
1826 be ignored by the rest of the module. (Bug #1078905).
1827
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001828- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001829 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001830
Walter Dörwald36733692004-12-22 12:50:50 +00001831- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1832 once when a size argument is given. This prevents a buffer overflow in the
1833 tokenizer with very long source lines.
1834
Barry Warsaw538561e2006-01-01 21:48:54 +00001835- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1836 immediately after creating the object, without any intervening
1837 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001838
Skip Montanaro05885812005-01-16 20:48:27 +00001839- The reconvert.quote function can now emit triple-quoted strings. The
1840 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001841
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001842- ``UserString.MutableString`` now supports negative indices in
1843 ``__setitem__`` and ``__delitem__``
1844
Greg Ward40407942005-03-05 02:53:17 +00001845- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1846 correctly.
1847
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001848- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1849 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1850 character even if the user has passed a size parameter to get a proper
1851 line ending. Remove the special handling of a "\r\n" that has been split
1852 between two lines.
1853
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001854- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1855 about illegal code points. The codec now supports PEP 293 style error
1856 handlers.
1857
Walter Dörwald78a78b02005-09-01 12:04:29 +00001858- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001859 from the input stream, so that the output is a byte string in the correct
1860 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001861
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001862- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1863 considering it exactly like a '*'.
1864
Walter Dörwald007f8df2005-10-09 19:42:27 +00001865- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1866 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001867
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001868- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1869
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001870- Patch #1413711: Certain patterns of differences were making difflib
1871 touch the recursion limit.
1872
Walter Dörwald58917a62006-03-31 15:26:22 +00001873- Bug #947906: An object oriented interface has been added to the calendar
1874 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001875 called as a script (e.g. via ``python -mcalendar``). Localized month and
1876 weekday names can be ouput (even if an exotic encoding is used) using
1877 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001878
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001879Build

1881
Neal Norwitz602d3392006-03-31 08:21:40 +00001882- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1883 by using -mieee gcc option.
1884

1886
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001887- Build support for Win64-AMD64 was added.
1888
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001889- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1890
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001891- Patch #881820: look for openpty and forkpty also in libbsd.
1892
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001893- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1894 The zlib module is now builtin on Windows.
1895
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001896- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1897
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001898- Bug #1189330: configure did not correctly determine the necessary
1899 value of LINKCC if python was built with GCC 4.0.
1900
Trent Mick8321b422005-07-26 02:29:21 +00001901- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1902 vulnerability in zlib 1.2.1 and 1.2.2.
1903
Brett Cannon08cd5982005-04-24 22:26:38 +00001904- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1905 flags that change binary compatibility. Changes were also made to
1906 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001907 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001908
Bob Ippolitoed233462005-03-29 13:47:59 +00001909- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1910 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1911 no longer exists). This configure patch makes things right.
1912
Martin v. Löwise2713be2005-03-08 15:03:08 +00001913- Bug #1158607: Build with --disable-unicode again.
1914
Brett Cannon46d96232005-02-16 00:07:19 +00001915- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1916 defined. Discovered as a result of not being able to build on OS X.
1917
Brett Cannon516592f2004-12-07 00:42:59 +00001918- setup.py now uses the directories specified in LDFLAGS using the -L option
1919 and in CPPFLAGS using the -I option for adding library and include
1920 directories, respectively, for compiling extension modules against. This has
1921 led to the core being compiled using the values in CPPFLAGS. It also removes
1922 the need for the special-casing of both DarwinPorts and Fink for darwin since
1923 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1924 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1925 Fink, ``-I/opt/local/include`` for DarwinPorts).
1926
Brett Cannon43802422005-02-10 20:48:03 +00001927- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1928 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1929 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1930 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001932C API
1933-----
1934
Tim Petersc9d78aa2006-03-26 23:27:58 +00001935- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1936 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1937 is obtained via the ``PyObject_`` family, it must be released via the
1938 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1939 always been officially true, but when Python's small-object allocator was
1940 introduced, an attempt was made to cater to a few extension modules
1941 discovered at the time that obtained memory via ``PyObject_New`` but
1942 released it via ``PyMem_DEL``. It's years later, and if such code still
1943 exists it will fail now (probably with segfaults, but calling wrong
1944 low-level memory management functions can yield many symptoms).
1945
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001946- Added a C API for set and frozenset objects.
1947
Raymond Hettinger66517482004-12-03 11:45:13 +00001948- Removed PyRange_New().
1949
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001950- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1951 mapping argument now. This string is used as a mapping table. Byte values
1952 greater than the length of the string and 0xFFFE are treated as undefined
1953 mappings.
