Marc-André Lemburg040f76b2006-08-14 10:55:19 +000031- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +000032 compared equal or unequal to a string and a UnicodeDecodeError
33 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +000034
Marc-André Lemburg040f76b2006-08-14 10:55:19 +000035 Instead, the equal (==) and unequal (!=) comparison operators will
36 now issue a UnicodeWarning and interpret the two objects as
37 unequal. The UnicodeWarning can be filtered as desired using
38 the warning framework, e.g. silenced completely, turned into an
39 exception, logged, etc.
40
41 Note that compare operators other than equal and unequal will still
42 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +000043
Marc-André Lemburg757ea272006-08-14 11:44:34 +000044- Fix segfault when doing string formatting on subclasses of long.
45
46- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
47 with new-style classes.
48
49- Fix bug related to __len__ functions returning negative values with
50 classic classes.
51
52- Patch #1538606, Fix __index__() clipping. There were some problems
53 discovered with the API and how integers that didn't fit into Py_ssize_t
54 were handled. This patch attempts to provide enough alternatives
55 to effectively use __index__.
56
Martin v. Löwisab2f8f72006-08-09 07:57:39 +000057- Bug #1536021: __hash__ may now return long int; the final hash
58 value is obtained by invoking hash on the long int.
59
Thomas Hellerab1049c2006-08-08 17:37:00 +000060- Bug #1536786: buffer comparison could emit a RuntimeWarning.
61
Georg Brandl7e3ba2a2006-08-06 08:23:54 +000062- Bug #1535165: fixed a segfault in input() and raw_input() when
63 sys.stdin is closed.
64
Thomas Heller74d36f02006-08-04 18:17:40 +000065- On Windows, the PyErr_Warn function is now exported from
66 the Python dll again.
67
Neal Norwitz4ffedad2006-08-04 04:58:47 +000068- Bug #1191458: tracing over for loops now produces a line event
69 on each iteration. Fixing this problem required changing the .pyc
70 magic number. This means that .pyc files generated before 2.5c1
71 will be regenerated.
72
Neal Norwitz0cbd8052006-08-04 05:09:28 +000073- Bug #1333982: string/number constants were inappropriately stored
74 in the byte code and co_consts even if they were not used, ie
75 immediately popped off the stack.
76
Georg Brandle9462c72006-08-04 18:03:37 +000077- Fixed a reference-counting problem in property().
78
Neal Norwitzff4b63b2006-08-04 04:50:21 +000079
80Library
81-------
82
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +000083- Fix a bug in the ``compiler`` package that caused invalid code to be
84 generated for generator expressions.
85
Marc-André Lemburg574cfea2006-08-16 16:11:01 +000086- The distutils version has been changed to 2.5.0. The change to
87 keep it programmatically in sync with the Python version running
88 the code (introduced in 2.5b3) has been reverted. It will continue
89 to be maintained manually as static string literal.
90
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +000091- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +000092 and this cannot be converted to the required C type, an exception is
93 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +000094 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +000095
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +000096- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +000097 an exception.
98
Anthony Baxter58179592006-08-16 13:08:25 +000099- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000100 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000101 workarounds for clocks with low resolution, to stop the code yielding
102 duplicate UUIDs.
103
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000104- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
105 before raising SystemExit, allowing IDLE to honor quit() and exit().
106
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000107- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
108
Georg Brandl7a1af772006-08-14 21:55:28 +0000109- Patch #1536071: trace.py should now find the full module name of a
110 file correctly even on Windows.
111
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000112- logging's atexit hook now runs even if the rest of the module has
113 already been cleaned up.
114
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000115- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000116
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000117- Bug #1531405, format_exception no longer raises an exception if
118 str(exception) raised an exception.
119
Neil Schemenauer06ded092006-08-04 16:20:30 +0000120- Fix a bug in the ``compiler`` package that caused invalid code to be
121 generated for nested functions.
122
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000123

128
Georg Brandl3335a7a2006-08-14 21:42:55 +0000129- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
130 raises the correct exceptions.
131
Thomas Heller1ce433e2006-08-14 16:20:04 +0000132- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
133 '-no-stack-protector' compiler flag for OpenBSD has been removed.
134
Thomas Heller86720042006-08-14 11:17:48 +0000135- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
136 uses the _as_parameter_ attribute when objects are passed to foreign
137 function calls. The ctypes version number was changed to 1.0.1.
138
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000139- Bug #1530559, struct.pack raises TypeError where it used to convert.
140 Passing float arguments to struct.pack when integers are expected
141 now triggers a DeprecationWarning.
142
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000143

165-----
166
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000167- Bug #1535502, build _hashlib on Windows, and use masm assembler
168 code in OpenSSL.
169

Neal Norwitza1f10902006-07-12 07:28:29 +0000192
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000193*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000194
195Core and builtins
196-----------------
197
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000198- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000199 returned a long (see PEP 353).
200
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000201- Bug #1515471: string.replace() accepts character buffers again.
202
Neal Norwitz07aadb12006-07-30 06:55:48 +0000203- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
204 This provides the proper warning for struct.pack().
205 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
206
Neal Norwitz0d62a062006-07-30 06:53:31 +0000207- Patch #1531113: Fix augmented assignment with yield expressions.
208 Also fix a SystemError when trying to assign to yield expressions.
209
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000210- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
211 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
212 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
213 excessive filesystem operations during imports.
214
Tim Petersbc24eee2006-07-27 01:14:53 +0000215- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
216 operations on signed longs that are formally undefined by C.
217 Unfortunately, at least one compiler now cares about that, so complicated
218 the code to make that compiler happy again.
219
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000220- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
221
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000222- Patch #1232023: Stop including current directory in search
223 path on Windows.
224
Neal Norwitze1fdb322006-07-21 05:32:28 +0000225- Fix some potential crashes found with failmalloc.
226
Neal Norwitze7563102006-07-17 01:00:16 +0000227- Fix warnings reported by Klocwork's static analysis tool.
228
Neal Norwitz84be93b2006-07-16 01:50:38 +0000229- Bug #1512814, Fix incorrect lineno's when code within a function
230 had more than 255 blank lines.
231
Georg Brandl9dceedb2006-07-12 15:31:17 +0000232- Patch #1521179: Python now accepts the standard options ``--help`` and
233 ``--version`` as well as ``/?`` on Windows.
234
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000235- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000236 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000237 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000238
Tim Peters112aad32006-07-19 00:03:19 +0000239- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000240 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000241 new ``sys._current_frames()`` returns a dictionary with one entry,
242 mapping the faux "thread id" 0 to the current frame.
243
Ronald Oussoren3075e162006-07-25 20:28:55 +0000244- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000245
Ronald Oussoren3075e162006-07-25 20:28:55 +0000246
Neal Norwitza1f10902006-07-12 07:28:29 +0000247Library
248-------
249
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000250- Correction of patch #1455898: In the mbcs decoder, set final=False
251 for stream decoder, but final=True for the decode function.
252
Georg Brandl07fec3a2006-08-01 18:49:24 +0000253- os.urandom no longer masks unrelated exceptions like SystemExit or
254 KeyboardInterrupt.
255
Tim Peters4643c2f2006-08-10 22:45:34 +0000256- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000257 shutil.copytree on Windows
258
Georg Brandle34ac7c2006-07-30 11:07:23 +0000259- Bug #1002398: The documentation for os.path.sameopenfile now correctly
260 refers to file descriptors, not file objects.
261
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000262- The renaming of the xml package to xmlcore, and the import hackery done
263 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000264 #1513611, and probably others.
265
Georg Brandledd9b0d2006-07-29 09:33:26 +0000266- Bug #1441397: The compiler module now recognizes module and function
267 docstrings correctly as it did in Python 2.4.
268
Tim Peters6f681472006-07-27 23:44:37 +0000269- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
270 lost that tests are sorted by name before being run. This rarely
271 matters for well-written tests, but can create baffling symptoms if
272 side effects from one test to the next affect outcomes. ``DocTestFinder``
273 has been changed to sort the list of tests it returns.
274
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000275- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000276 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000277
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000278- Bug #978833: Really close underlying socket in _socketobject.close.
279
Georg Brandl0619a322006-07-26 07:40:17 +0000280- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
281 with title().
282
Georg Brandlcf0c1722006-07-26 07:23:32 +0000283- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
284 to recursive calls and call it with the failing package name.
285
Martin v. Löwis0b483032006-07-25 09:53:12 +0000286- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
287
Georg Brandlc13c34c2006-07-24 14:09:56 +0000288- Patch #1515343: Fix printing of deprecated string exceptions with a
289 value in the traceback module.
290
Greg Ward48fae7a2006-07-23 16:05:51 +0000291- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
292
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000293- Patch #1524429: Use repr() instead of backticks in Tkinter again.
294
Brett Cannoncaebe222006-07-18 04:41:36 +0000295- Bug #1520914: Change time.strftime() to accept a zero for any position in its
296 argument tuple. For arguments where zero is illegal, the value is forced to
297 the minimum value that is correct. This is to support an undocumented but
298 common way people used to fill in inconsequential information in the time
299 tuple pre-2.4.
300
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000301- Patch #1220874: Update the binhex module for Mach-O.
302
Barry Warsawb110bad2006-07-21 14:51:07 +0000303- The email package has improved RFC 2231 support, specifically for
304 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
305 (name*0=<blah>) parameter continuations. This may change the types of
306 values returned from email.message.Message.get_param() and friends.
307 Specifically in some cases where non-encoded continuations were used,
308 get_param() used to return a 3-tuple of (None, None, string) whereas now it
309 will just return the string (since non-encoded continuations don't have
310 charset and language parts).
311
312 Also, whereas % values were decoded in all parameter continuations, they are
313 now only decoded in encoded parameter parts.

Ronald Oussoren3075e162006-07-25 20:28:55 +0000315- Bug #1517990: IDLE keybindings on MacOS X now work correctly
316
317- Bug #1517996: IDLE now longer shows the default Tk menu when a
318 path browser, class browser or debugger is the frontmost window on MacOS X
319
Barry Warsaw00decd72006-07-27 23:43:15 +0000320- Patch #1520294: Support for getset and member descriptors in types.py,
321 inspect.py, and pydoc.py. Specifically, this allows for querying the type
322 of an object against these built-in types and more importantly, for getting
323 their docstrings printed in the interactive interpreter's help() function.

327-----------------
328
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000329- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
330 a socket operation on a socket with a timeout, the exception will be
331 caught correctly. Previously, the exception was not caught.
332
Thomas Heller1393d6a2006-07-28 21:43:20 +0000333- Patch #1529514: The _ctypes extension is now compiled on more
334 openbsd target platforms.
335
Tim Peters9cab5932006-07-28 00:30:00 +0000336- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
337 a memory leak, affecting pickles and deep copies.
338
Tim Petersbc24eee2006-07-27 01:14:53 +0000339- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

343
Thomas Hellerce049a02006-07-14 17:51:14 +0000344- Patch #1521817: Index range checking on ctypes arrays containing
345 exactly one element enabled again. This allows iterating over these
346 arrays, without the need to check the array size before.
347
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000348- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000349 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000350 /dev/null in certain cases; this is now fixed.
351
Thomas Heller47d7a062006-07-12 08:43:47 +0000352- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
353 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000354
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000355- Because of a misspelled preprocessor symbol, ctypes was always
356 compiled without thread support; this is now fixed.
357
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000358- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
359 methods now allow their database parameter to be None as the
360 sleepycat API allows.
361
Matt Flemingec926502006-07-28 11:27:27 +0000362- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
363 bluetooth API compared with Linux and FreeBSD.
364
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000365Tests
366-----
367
368- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
369 how long the test file should take to play. Now accepts taking 2.93 secs
370 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
371
Georg Brandl4793aa32006-07-28 18:31:39 +0000372- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
373 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
374 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000381Mac
382---
383
384- PythonLauncher now works correctly when the path to the script contains
385 characters that are treated specially by the shell (such as quotes).
386
387- Bug #1527397: PythonLauncher now launches scripts with the working directory
388 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000389 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000390 expect.

398Core and builtins
399-----------------
400
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000401- Bug #1441486: The literal representation of -(sys.maxint - 1)
402 again evaluates to a int object, not a long.
403
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000404- Bug #1501934: The scope of global variables that are locally assigned
405 using augmented assignment is now correctly determined.
406
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000407- Bug #927248: Recursive method-wrapper objects can now safely
408 be released.
409
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000410- Bug #1417699: Reject locale-specific decimal point in float()
411 and atof().
412
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000413- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
414 omit a default "error" argument for NULL pointer. This allows
415 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000416
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000417- Bug #1519018: 'as' is now validated properly in import statements.
418
Neal Norwitz28746ab2006-07-09 22:14:42 +0000419- On 64 bit systems, int literals that use less than 64 bits are
420 now ints rather than longs.
421
Neal Norwitzed657552006-07-10 00:04:44 +0000422- Bug #1512814, Fix incorrect lineno's when code at module scope
423 started after line 256.
424
Tim Peters32a83612006-07-10 21:08:24 +0000425- New function ``sys._current_frames()`` returns a dict mapping thread
426 id to topmost thread stack frame. This is for expert use, and is
427 especially useful for debugging application deadlocks. The functionality
428 was previously available in Fazal Majid's ``threadframe`` extension
429 module, but it wasn't possible to do this in a wholly threadsafe way from
430 an extension.

447
Thomas Woutersadd19112006-07-05 11:03:49 +0000448- string.Template() now correctly handles tuple-values. Previously,
449 multi-value tuples would raise an exception and single-value tuples would
450 be treated as the value they contain, instead.
451
Martin v. Löwisede77f52006-07-03 13:01:35 +0000452- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
453 even if some data are received.

459 degrees and radians.
460
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000461- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000462 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000463

465 is created.
466
Martin v. Löwis7596e832006-07-01 15:33:37 +0000467- Bug #1513223: .close() of a _socketobj now releases the underlying
468 socket again, which then gets closed as it becomes unreferenced.
469
Fred Drake10497c82006-06-29 02:57:48 +0000470- Bug #1504333: Make sgmllib support angle brackets in quoted
471 attribute values.
472
473- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
474 sgmllib ('[' and ']' were not accepted).
475
Georg Brandl1be63af2006-06-28 20:23:25 +0000476- Fix a bug in the turtle module's end_fill function.
477
Brett Cannon53ab5b72006-06-22 16:49:14 +0000478- Bug #1510580: The 'warnings' module improperly required that a Warning
479 category be either a types.ClassType and a subclass of Warning. The proper
480 check is just that it is a subclass with Warning as the documentation states.
481
Georg Brandlad29e632006-06-21 17:45:17 +0000482- The compiler module now correctly compiles the new try-except-finally
483 statement (bug #1509132).
484
Neal Norwitz60373cd2006-06-22 06:30:50 +0000485- The wsgiref package is now installed properly on Unix.
486
Vinay Sajip28e57612006-07-01 10:45:20 +0000487- A bug was fixed in logging.config.fileConfig() which caused a crash on
488 shutdown when fileConfig() was called multiple times.
489
Gerhard Häring762fbd32006-07-02 17:48:30 +0000490- The sqlite3 module did cut off data from the SQLite database at the first
491 null character before sending it to a custom converter. This has been fixed
492 now.

495-----------------
496
Tim Peters112aad32006-07-19 00:03:19 +0000497- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
498 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
499 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000500
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000501- Assigning None to pointer type fields in ctypes structures possible
502 overwrote the wrong fields, this is fixed now.
503
504- Fixed a segfault in _ctypes when ctypes.wintypes were imported
505 on non-Windows platforms.
506
507- Bug #1518190: The ctypes.c_void_p constructor now accepts any
508 integer or long, without range checking.
509
510- Patch #1517790: It is now possible to use custom objects in the ctypes
511 foreign function argtypes sequence as long as they provide a from_param
512 method, no longer is it required that the object is a ctypes type.
513
514- The '_ctypes' extension module now works when Python is configured
515 with the --without-threads option.
516
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000517- Bug #1513646: os.access on Windows now correctly determines write
518 access, again.
519
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000520- Bug #1512695: cPickle.loads could crash if it was interrupted with
521 a KeyboardInterrupt.
522
Neal Norwitza12aa882006-07-06 06:45:08 +0000523- Bug #1296433: parsing XML with a non-default encoding and
524 a CharacterDataHandler could crash the interpreter in pyexpat.

530
Martin v. Löwisd73168d2006-07-14 09:58:55 +0000531- Automate Windows build process for the Win64 SSL module.
532
Tim Peters32a83612006-07-10 21:08:24 +0000533- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000534 Previously, the slight difference could cause compilation errors of the
535 'zlib' module on systems with more than one version of zlib.
536
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000537- The MSI compileall step was fixed to also support a TARGETDIR
538 with spaces in it.

541 of Tcl/Tk.
542
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000543- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old

569-----------------
570
Georg Brandla56b9152006-06-19 06:35:54 +0000571- Patch #1507676: Error messages returned by invalid abstract object operations
572 (such as iterating over an integer) have been improved and now include the
573 type of the offending object to help with debugging.
574
Brett Cannonea3912b2006-06-13 21:46:41 +0000575- Bug #992017: A classic class that defined a __coerce__() method that returned
576 its arguments swapped would infinitely recurse and segfault the interpreter.
577
Neal Norwitz909eb122006-06-12 02:13:21 +0000578- Fix the socket tests so they can be run concurrently.
579
Neal Norwitzb9845e72006-06-12 02:11:18 +0000580- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000581 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000582
Brett Cannon22565aa2006-06-09 22:31:23 +0000583- Bug #532646: object.__call__() will continue looking for the __call__
584 attribute on objects until one without one is found. This leads to recursion
585 when you take a class and set its __call__ attribute to an instance of the
586 class. Originally fixed for classic classes, but this fix is for new-style.
587 Removes the infinite_rec_3 crasher.
588
Georg Brandl24250812006-06-09 18:45:48 +0000589- The string and unicode methods startswith() and endswith() now accept
590 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
591
Brett Cannonde3b0522006-06-08 17:00:45 +0000592- Buffer objects, at the C level, never used the char buffer
593 implementation even when the char buffer for the wrapped object was
594 explicitly requested (originally returned the read or write buffer).
595 Now a TypeError is raised if the char buffer is not present but is
596 requested.
597
Georg Brandlddbaa662006-06-04 21:56:52 +0000598- Patch #1346214: Statements like "if 0: suite" are now again optimized
599 away like they were in Python 2.4.
600
Georg Brandlb7c8f542006-05-27 12:30:25 +0000601- Builtin exceptions are now full-blown new-style classes instead of
602 instances pretending to be classes, which speeds up exception handling
603 by about 80% in comparison to 2.5a2.
604
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000605- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
606 Unicode 4.1.
607
Georg Brandlf4ef1162006-05-26 18:03:31 +0000608- Patch #921466: sys.path_importer_cache is now used to cache valid and
609 invalid file paths for the built-in import machinery which leads to
610 fewer open calls on startup.
611
Tim Peters696cf432006-05-24 21:10:40 +0000612- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
613 of-2 bases. The largest speedup is for inputs with about 1000 decimal
614 digits. Conversion from non-power-of-2 bases remains quadratic-time in
615 the number of input digits (it was and remains linear-time for bases
616 2, 4, 8, 16 and 32).
617
Tim Petersb713ec22006-05-23 18:45:30 +0000618- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
619 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
620 an integer close to ``sys.maxint``. This was repaired by patch
621 #1335972, which also gives a nice speedup.
622
Richard Jonescebbefc2006-05-23 18:28:17 +0000623- Patch #1337051: reduced size of frame objects.
624
625- PyErr_NewException now accepts a tuple of base classes as its
626 "base" parameter.
627
Richard Jones7c88dcc2006-05-23 10:37:38 +0000628- Patch #876206: function call speedup by retaining allocated frame
629 objects.
630
Georg Brandl7b90e162006-05-18 07:01:27 +0000631- Bug #1462152: file() now checks more thoroughly for invalid mode
632 strings and removes a possible "U" before passing the mode to the
633 C library function.
634
Neal Norwitz1004a532006-05-15 07:17:23 +0000635- Patch #1488312, Fix memory alignment problem on SPARC in unicode
636
Neal Norwitz373f0a72006-05-15 07:04:36 +0000637- Bug #1487966: Fix SystemError with conditional expression in assignment
638
Martin v. Löwis879768d2006-05-11 13:28:43 +0000639- WindowsError now has two error code attributes: errno, which carries
640 the error values from errno.h, and winerror, which carries the error
641 values from winerror.h. Previous versions put the winerror.h values
642 (from GetLastError()) into the errno attribute.
643
Martin v. Löwis77736712006-05-04 05:51:03 +0000644- Patch #1475845: Raise IndentationError for unexpected indent.
645
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000646- Patch #1479181: split open() and file() from being aliases for each other.
647
Tim Peters44bd9862006-06-01 13:49:23 +0000648- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
649 methods were always silently ignored by dictionaries when comparing keys.
650 They are now passed through (except when using the C API function
651 ``PyDict_GetItem()``, whose semantics did not change).
652
653- Bug #1456209: In some obscure cases it was possible for a class with a
654 custom ``__eq__()`` method to confuse dict internals when class instances
655 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
656 No, you don't have any code that did this ;-)

659-----------------
660
Trent Mick960a3f82006-06-28 20:30:41 +0000661- Bug #1295808: expat symbols should be namespaced in pyexpat
662
663- Patch #1462338: Upgrade pyexpat to expat 2.0.0
664
Brett Cannon6ee7d012006-06-08 16:23:04 +0000665- Change binascii.hexlify to accept a read-only buffer instead of only a char
666 buffer and actually follow its documentation.
667
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000668- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
669
Nick Coghlanc649ec52006-05-29 12:43:05 +0000670- Patch #1478788 (modified version): The functional extension module has
671 been renamed to _functools and a functools Python wrapper module added.
672 This provides a home for additional function related utilities that are
673 not specifically about functional programming. See PEP 309.
674
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000675- Patch #1493701: performance enhancements for struct module.
676
Georg Brandl378d5922006-05-17 14:26:50 +0000677- Patch #1490224: time.altzone is now set correctly on Cygwin.
678
Georg Brandl8d3342b2006-05-16 07:38:27 +0000679- Patch #1435422: zlib's compress and decompress objects now have a
680 copy() method.
681
Andrew MacIntyre92913322006-06-13 15:04:24 +0000682- Patch #1454481: thread stack size is now tunable at runtime for thread
683 enabled builds on Windows and systems with Posix threads support.
684
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000685- On Win32, os.listdir now supports arbitrarily-long Unicode path names
686 (up to the system limit of 32K characters).
687
688- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
689 As a result, these functions now raise WindowsError instead of OSError.
690
Tim Peters7a822da2006-05-25 21:50:17 +0000691- ``time.clock()`` on Win64 should use the high-performance Windows
692 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
693 Windows platforms).
694
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000695- Calling Tk_Init twice is refused if the first call failed as that
696 may deadlock.
697
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000698- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
699 accept it without potentially using an uninitialized pointer.
700
701- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
702 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
703 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000704
Gregory P. Smith372b5832006-06-05 18:48:21 +0000705- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000706 [pybsddb project SF patch number 1466734]
707
Gregory P. Smith372b5832006-06-05 18:48:21 +0000708- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
709 parameter is supplied. [SF pybsddb bug #1477863]
710
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000711- bsddb: the __len__ method of a DB object has been fixed to return correct
712 results. It could previously incorrectly return 0 in some cases.
713 Fixes SF bug 1493322 (pybsddb bug 1184012).
714
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000715- bsddb: the bsddb.dbtables Modify method now raises the proper error and
716 aborts the db transaction safely when a modifier callback fails.
717 Fixes SF python patch/bug #1408584.
718
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000719- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000720 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000721 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
722 database calls that would previously deadlock. [SF python bug #775414]
723
Vinay Sajip28e57612006-07-01 10:45:20 +0000724- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000725
Walter Dörwald4994d952006-06-19 08:07:50 +0000726- Patch #1506645: add Python wrappers for the curses functions
727 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000728

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000732- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
733 functions.
734
Martin v. Löwis3798da02006-06-17 18:44:27 +0000735- Patch #812986: Update turtle output even if not tracing.
736
Vinay Sajip28e57612006-07-01 10:45:20 +0000737- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +0000738 Tkinter.BaseWidget.
739
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000740- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
741
Martin v. Löwis337487e2006-06-17 09:15:14 +0000742- Patch #763580: Add name and value arguments to Tkinter variable
743 classes.
744
Georg Brandl83cc0d02006-06-14 08:50:03 +0000745- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
746 mime.types file for determining MIME types.
747
Georg Brandl2605ca82006-06-14 06:08:31 +0000748- Bug #1339007: Shelf objects now don't raise an exception in their
749 __del__ method when initialization failed.
750
Martin v. Löwisd8251432006-06-14 05:21:04 +0000751- Patch #1455898: The MBCS codec now supports the incremental mode for
752 double-byte encodings.
753
Tim Peters43898b42006-06-14 04:09:25 +0000754- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
755 guarantee that adjacent triples in the return list always describe
756 non-adjacent blocks. Previously, a pair of matching blocks could end
757 up being described by multiple adjacent triples that formed a partition
758 of the matching pair.
759
Greg Ward0e0c9f42006-06-11 16:24:11 +0000760- Bug #1498146: fix optparse to handle Unicode strings in option help,
761 description, and epilog.
762
Greg Wardd1c797e2006-06-11 14:42:41 +0000763- Bug #1366250: minor optparse documentation error.
764
Greg Ward7f547402006-06-11 00:40:49 +0000765- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
766 clarify docs.
767
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000768- The wsgiref package has been added to the standard library.
769
Nick Coghlan676725d2006-06-08 13:54:49 +0000770- The functions update_wrapper() and wraps() have been added to the functools
771 module. These make it easier to copy relevant metadata from the original
772 function when writing wrapper functions.
773
Tim Petersd6a9eef2006-06-05 01:48:21 +0000774- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
775 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000776
Martin v. Löwis3f767792006-06-04 19:36:28 +0000777- Patch #1359618: Speed up charmap encoder by using a trie structure
778 for lookup.
779
Tim Petersd609b1a2006-06-02 23:22:51 +0000780- The functions in the ``pprint`` module now sort dictionaries by key
781 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
782 if and only if its display required more than one line, although that
783 wasn't documented. The new behavior increases predictability; e.g.,
784 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
785
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000786- Patch #1497027: try HTTP digest auth before basic auth in urllib2
787 (thanks for J. J. Lee).
788
Georg Brandl2b330372006-05-28 20:23:12 +0000789- Patch #1496206: improve urllib2 handling of passwords with respect to
790 default HTTP and HTTPS ports.
791
George Yoshidaf3c65de2006-05-28 16:39:09 +0000792- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
793
Bob Ippolito7298f272006-05-23 18:43:47 +0000794- Patch #1281707: speed up gzip.readline.
795
Georg Brandlb89316f2006-05-17 15:51:16 +0000796- Patch #1180296: Two new functions were added to the locale module:
797 format_string() to get the effect of "format % items" but locale-aware,
798 and currency() to format a monetary number with currency sign.
799
Georg Brandle3a25832006-05-17 14:56:04 +0000800- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
801 and several features added, such as speed and geometry control.
802
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000803- Patch #1488881: add support for external file objects in bz2 compressed
804 tarfiles.
805
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000806- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
807 stdout arguments, making it possible to redirect input and output
808 for remote debugging.
809
810- Patch #1484695: Update the tarfile module to version 0.8. This fixes
811 a couple of issues, notably handling of long file names using the
812 GNU LONGNAME extension.
813
814- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
815 new flag when ``name`` is already the name of an option flag.
816
817- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
818 package.
819
820- Patch #1472854: make the rlcompleter.Completer class usable on non-
821 UNIX platforms.
822
823- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
824
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000825- Bug #1472827: correctly escape newlines and tabs in attribute values in
826 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000856What's New in Python 2.5 alpha 2?
857=================================
858
859*Release date: 27-APR-2006*
860
861Core and builtins
862-----------------
863
Thomas Heller1b046642006-04-18 18:51:06 +0000864- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
865 by converting these apis from macros into exported functions again:
866
867 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
868 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
869 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
870 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
871 PyRun_String Py_CompileString
872
Martin v. Löwis45294a92006-04-18 06:24:08 +0000873- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
874
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000875- All uses of PyStructSequence_InitType have been changed to initialize
876 the type objects only once, even if the interpreter is initialized
877 multiple times.
878
Neal Norwitz61546162006-04-14 05:20:28 +0000879- Bug #1454485, array.array('u') could crash the interpreter. This was
880 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
881 to unicode when it didn't make sense. 'u#' now requires a unicode string.
882
883- Py_UNICODE is unsigned. It was always documented as unsigned, but
884 due to a bug had a signed value in previous versions.
885
Tim Peters3a5e8b12006-04-11 01:44:07 +0000886- Patch #837242: ``id()`` of any Python object always gives a positive
887 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
888 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000889 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000890 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000891
Tim Peters3a5e8b12006-04-11 01:44:07 +0000892 def __hash__(self):
893 return id(self) # WRONG
894
895 because a hash result must be a (short) Python int but it was always
896 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000897 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000898 was always usable as a hash value before this patch. That's no longer
899 necessarily so.
900
901- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000902 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000903 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000904 #1454844)
905
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000906- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
907 involving generators that have paused outside of any ``try`` or ``with``
908 blocks. (In 2.5a1, a paused generator that was part of a reference
909 cycle could not be garbage collected, regardless of whether it was
910 paused in a ``try`` or ``with`` block.)

913-----------------
914
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000915- Patch #1191065: Fix preprocessor problems on systems where recvfrom
916 is a macro.
917
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000918- Bug #1467952: os.listdir() now correctly raises an error if readdir()
919 fails with an error condition.
920
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000921- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
922
923- Bug #1117761: bsddb.*open() no longer raises an exception when using
924 the cachesize parameter.
925
926- Bug #1149413: bsddb.*open() no longer raises an exception when using
927 a temporary db (file=None) with the 'n' flag to truncate on open.
928
929- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
930 as older versions cause excessive test failures.

936-------
937
Peter Astrand7d1d4362006-07-14 14:04:45 +0000938- Bug #1223937: subprocess.CalledProcessError reports the exit status
939 of the process using the returncode attribute, instead of
940 abusing errno.
941
Tim Peters711bf302006-04-25 03:31:36 +0000942- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
943 a doctest to be skipped (the code is not run, and the expected output
944 or exception is ignored).
945
Nick Coghlanda2268f2006-04-24 04:37:15 +0000946- Fixed contextlib.nested to cope with exceptions being raised and
947 caught inside exit handlers.
948
Greg Wardab05edc2006-04-23 03:47:58 +0000949- Updated optparse module to Optik 1.5.1 (allow numeric constants in
950 hex, octal, or binary; add ``append_const`` action; keep going if
951 gettext cannot be imported; added ``OptionParser.destroy()`` method;
952 added ``epilog`` for better help generation).
953
Tim Peters21fbd572006-04-21 21:18:10 +0000954- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
955 called from a thread spawned as a side effect of importing a module.
956
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000957- The pydoc module now supports documenting packages contained in
958 .zip or .egg files.
959
960- The pkgutil module now has several new utility functions, such
961 as ``walk_packages()`` to support working with packages that are either
962 in the filesystem or zip files.
963
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000964- The mailbox module can now modify and delete messages from
965 mailboxes, in addition to simply reading them. Thanks to Gregory
966 K. Johnson for writing the code, and to the 2005 Google Summer of
967 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000968
Tim Petersc7605f22006-04-17 21:12:33 +0000969- The ``__del__`` method of class ``local`` in module ``_threading_local``
970 returned before accomplishing any of its intended cleanup.

Anthony Baxtere29002c2006-04-12 12:07:31 +0000978- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
979 Windows. Bug #1469163.
980
Phillip J. Eby47032112006-04-11 01:07:43 +0000981- The warnings, linecache, inspect, traceback, site, and doctest modules
982 were updated to work correctly with modules imported from zipfiles or
983 via other PEP 302 __loader__ objects.
984

993 direct output to an alternate file-like object.
994
Anthony Baxter51bcb682006-04-05 14:51:42 +0000995Build
996-----
997
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000998- The Makefile now has a reindent target, which runs reindent.py on
999 the library.
1000
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001001- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001004
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001005- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1006 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001007 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001008 CXX from --with-cxx-main, see description in README.
1009
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001010- Patch #1429775: Link extension modules with the shared libpython.
1011
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001012- Fixed a libffi build problem on MIPS systems.
1013
Tim Peters8931ff12006-05-13 23:28:20 +00001014- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1015 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1016 and "%zu" for unsigned integers of type ``size_t``.
1017
Anthony Baxter51bcb682006-04-05 14:51:42 +00001018Tests
1019-----
1020
Nick Coghlanda2268f2006-04-24 04:37:15 +00001021- test_contextlib now checks contextlib.nested can cope with exceptions
1022 being raised and caught inside exit handlers.
1023
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001024- test_cmd_line now checks operation of the -m and -c command switches
1025
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001026- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1027 it separately and by hand. It also wasn't cleaning up its changes to
1028 the current Decimal context.
1029
Thomas Woutersabd08882006-04-26 15:53:30 +00001030- regrtest.py now has a -M option to run tests that test the new limits of
1031 containers, on 64-bit architectures. Running these tests is only sensible
1032 on 64-bit machines with more than two gigabytes of memory. The argument
1033 passed is the maximum amount of memory for the tests to use.

1042-------------
1043
Tim Petersb06d28c2006-05-12 01:57:59 +00001044- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1045
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001046- PEP 343: Added Context Types section to the library reference
1047 and attempted to bring other PEP 343 related documentation into
1048 line with the implementation and/or python-dev discussions.
1049
Tim Peters8dc73d22006-04-24 02:03:16 +00001050- Bug #1337990: clarified that ``doctest`` does not support examples
1051 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001054What's New in Python 2.5 alpha 1?
1055=================================
1056
Anthony Baxterebed3f62006-04-03 15:03:44 +00001057*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001058
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001059Core and builtins
1060-----------------
1061
Nick Coghlan43832302006-04-23 17:04:07 +00001062- PEP 338: -m command line switch now delegates to runpy.run_module
1063 allowing it to support modules in packages and zipfiles
1064
Martin v. Löwisc661b882006-04-20 04:54:23 +00001065- On Windows, .DLL is not an accepted file name extension for
1066 extension modules anymore; extensions are only found if they
1067 end in .PYD.
1068
Martin v. Löwisea62d252006-04-03 10:56:49 +00001069- Bug #1421664: sys.stderr.encoding is now set to the same value as
1070 sys.stdout.encoding.
1071
Neal Norwitz92e212f2006-04-03 04:48:37 +00001072- __import__ accepts keyword arguments.
1073
Georg Brandlccadf842006-03-31 18:54:53 +00001074- Patch #1460496: round() now accepts keyword arguments.
1075
Anthony Baxter262c00a2006-03-30 10:53:17 +00001076- Fixed bug #1459029 - unicode reprs were double-escaped.
1077
Hye-Shik Changd478f342006-03-23 12:32:36 +00001078- Patch #1396919: The system scope threads are reenabled on FreeBSD
1079 5.4 and later versions.
1080
Neal Norwitze98ccf62006-03-23 05:39:47 +00001081- Bug #1115379: Compiling a Unicode string with an encoding declaration
1082 now gives a SyntaxError.
1083
Georg Brandlabd1ff82006-03-18 07:59:59 +00001084- Previously, Python code had no easy way to access the contents of a
1085 cell object. Now, a ``cell_contents`` attribute has been added
1086 (closes patch #1170323).
1087
Tim Peterscf79aac2006-03-16 01:14:46 +00001088- Patch #1123430: Python's small-object allocator now returns an arena to
1089 the system ``free()`` when all memory within an arena becomes unused
1090 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1091 freed. Some applications will see a drop in virtual memory size now,
1092 especially long-running applications that, from time to time, temporarily
1093 use a large number of small objects. Note that when Python returns an
1094 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001095 platform C library will in turn return that memory to the operating system.
1096 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001097 appears to be effective at least on Microsoft C and gcc-based systems.
1098 Thanks to Evan Jones for hard work and patience.
1099
Georg Brandl533ff6f2006-03-08 18:09:27 +00001100- Patch #1434038: property() now uses the getter's docstring if there is
1101 no "doc" argument given. This makes it possible to legitimately use
1102 property() as a decorator to produce a read-only property.
1103
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001104- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1105 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1106 of requiring an int or long in slicing and a few other contexts, enabling
1107 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1108
Neal Norwitz995acdf2006-03-07 05:01:00 +00001109- Fixed various bugs reported by Coverity's Prevent tool.
1110
Brett Cannonbf364092006-03-01 04:25:17 +00001111- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1112 new exception base class, BaseException, which has a new message attribute.
1113 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1114 Raising a string exception now raises a DeprecationWarning.
1115
Thomas Woutersfb609f42006-02-28 16:37:25 +00001116- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1117 explicitly relative, using 'from .module import name' to mean 'from the same
1118 package as this module is in. Imports without dots still default to the
1119 old relative-then-absolute, unless 'from __future__ import
1120 absolute_import' is used.
1121
Brett Cannona7446e32006-02-27 23:39:10 +00001122- Properly check if 'warnings' raises an exception (usually when a filter set
1123 to "error" is triggered) when raising a warning for raising string
1124 exceptions.
1125
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001126- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001127 The name was removed from Include/code.h.
1128
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001129- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001130
Guido van Rossum1968ad32006-02-25 22:38:04 +00001131- Patch 1433928:
1132 - The copy module now "copies" function objects (as atomic objects).
1133 - dict.__getitem__ now looks for a __missing__ hook before raising
1134 KeyError.
1135
Tim Peters84ef21c2006-02-28 20:39:06 +00001136- PEP 343: with statement implemented. Needs ``from __future__ import
1137 with_statement``. Use of 'with' as a variable will generate a warning.
1138 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001139 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001140 The following objects have __context__ methods:
1141 - The built-in file type.
1142 - The thread.LockType type.
1143 - The following types defined by the threading module:
1144 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1145 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001146
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001147- Fix the encodings package codec search function to only search
1148 inside its own package. Fixes problem reported in patch #1433198.
1149
1150 Note: Codec packages should implement and register their own
1151 codec search function. PEP 100 has the details.
1152
Tim Peters9ea89d22006-06-04 03:26:02 +00001153- PEP 353: Using ``Py_ssize_t`` as the index type.
1154
1155- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1156 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1157 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1158 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1159 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001160
Neal Norwitzfc76d632006-01-10 06:03:13 +00001161- Patch #1400181, fix unicode string formatting to not use the locale.
1162 This is how string objects work. u'%f' could use , instead of .
1163 for the decimal point. Now both strings and unicode always use periods.
1164
Neal Norwitz671b9e32006-01-09 07:07:12 +00001165- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1166 configure would break checking curses.h.
1167
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001168- Bug #959576: The pwd module is now builtin. This allows Python to be
1169 built on UNIX platforms without $HOME set.
1170
Neal Norwitzc10978f2005-12-19 06:07:16 +00001171- Bug #1072182, fix some potential problems if characters are signed.
1172
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001173- Bug #889500, fix line number on SyntaxWarning for global declarations.
1174
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001175- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1176
Neal Norwitze7214a12005-12-18 05:03:17 +00001177- Support for converting hex strings to floats no longer works.
1178 This was not portable. float('0x3') now raises a ValueError.
1179
Barry Warsaw2a38a862005-12-18 01:27:35 +00001180- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001181 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001182 is now displayed in interactive prompt banner.
1183
Georg Brandlfa166682005-12-17 21:45:17 +00001184- Implementation of PEP 341 - Unification of try/except and try/finally.
1185 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001186 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001187
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001188- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1189 now encodes backslash correctly.
1190
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001191- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1192
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001193- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001194 and long longs.
1195
Neal Norwitz67715f02005-11-09 06:59:35 +00001196- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001197 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001198 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001199
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001200- Replaced most Unicode charmap codecs with new ones using the
1201 new Unicode translate string feature in the builtin charmap
1202 codec; the codecs were created from the mapping tables available
1203 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1204 encodings now include a mapping for the Apple logo)
1205
Tim Peterse3547fd2005-12-16 23:13:57 +00001206- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001207
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001208- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001209
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001210- A new AST parser implementation was completed. The abstract
1211 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001212 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001213
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001214- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001215 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1216
Neal Norwitz708e51a2005-10-03 04:48:15 +00001217- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1218
Neal Norwitz11bd1192005-10-03 00:54:56 +00001219- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1220 Provide a warning when a directory is passed on the command line.
1221
Neal Norwitz40d37812005-10-02 01:48:49 +00001222- Fix segfault with invalid coding.
1223
1224- SF bug #772896: unknown encoding results in MemoryError.
1225
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001226- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001227 supported a __len__() method which evaluated to False when the iterator
1228 was empty.
1229
Guido van Rossum630db602005-09-20 18:49:54 +00001230- On 64-bit platforms, when __len__() returns a value that cannot be
1231 represented as a C int, raise OverflowError.
1232
Skip Montanarof8948ca2005-09-19 03:54:46 +00001233- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001234 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001235
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001236- SF bug #893549: parsing keyword arguments was broken with a few format
1237 codes.
1238
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001239- Changes donated by Elemental Security to make it work on AIX 5.3
1240 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1241 bug #105470: test_pwd fails on 64bit system (Opteron).
1242
Guido van Rossum539c6622005-09-14 17:49:54 +00001243- Changes donated by Elemental Security to make it work on HP-UX 11 on
1244 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1245
Georg Brandl4550b8d2005-08-26 06:43:52 +00001246- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001247 (fixes bug #1119418).
1248
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001249- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1250
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001251- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1252 exceptions that cause a function to exit.
1253
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001254- The implementation of set() and frozenset() was revised to use its
1255 own internal data structure. Memory consumption is reduced by 1/3
1256 and there are modest speed-ups as well. The API is unchanged.
1257
Tim Petersde7990b2005-07-17 23:45:23 +00001258- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1259
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001260- SF bug #1229429: PyObject_CallMethod failed to decrement some
1261 reference counts in some error exit cases.
1262
Tim Petersecc6e6a2005-07-10 22:30:55 +00001263- SF bug #1185883: Python's small-object memory allocator took over
1264 a block managed by the platform C library whenever a realloc specified
1265 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001266 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001267 portable way to copy data from the C-managed block into Python's
1268 small-object space without risking a memory fault. Python's small-object
1269 realloc now leaves such blocks under the control of the platform C
1270 realloc.
1271
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001272- SF bug #1232517: An overflow error was not detected properly when
1273 attempting to convert a large float to an int in os.utime().
1274
Raymond Hettinger3296e692005-06-29 23:29:56 +00001275- SF bug #1224347: hex longs now print with lowercase letters just
1276 like their int counterparts.
1277
Michael W. Hudson188d4362005-06-20 16:52:57 +00001278- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1279 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1280 interpreter states; back out that fix and do a better job (see
1281 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1282 for a longer write-up of the problem).
1283
Michael W. Hudsondf888462005-06-03 14:41:55 +00001284- SF patch #1180995: marshal now uses a binary format by default when
1285 serializing floats.
1286
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001287- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1288 the routines that promise to produce IEEE 754 binary representations
1289 of floats now simply copy bytes around.
1290
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001291- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1292 278.
1293
Brett Cannonc3647ac2005-04-26 03:45:26 +00001294- patch #1109424: int, long, float, complex, and unicode now check for the
1295 proper magic slot for type conversions when subclassed. Previously the
1296 magic slot was ignored during conversion. Semantics now match the way
1297 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001298 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001299 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001300 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001301
Barry Warsawc8d907c2005-04-19 23:43:40 +00001302- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1303 NULL, now raise an AttributeError when attempting to set or delete the
1304 attribute. Previously a TypeError was raised, but this was inconsistent
1305 with the equivalent pure-Python implementation.
1306
Michael W. Hudson774479c2005-04-18 08:46:17 +00001307- It is now safe to call PyGILState_Release() before
1308 PyEval_InitThreads() (note that if there is reason to believe there
1309 are multiple threads around you still must call PyEval_InitThreads()
1310 before using the Python API; this fix is for extension modules that
1311 have no way of knowing if Python is multi-threaded yet).
1312
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001313- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1314 disabled caused a crash.
1315
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001316- Bug #1165306: instancemethod_new allowed the creation of a method
1317 with im_class == im_self == NULL, which caused a crash when called.
1318
Tim Petersecc6e6a2005-07-10 22:30:55 +00001319- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001320 fixes the crash seen in bug #1165761
1321
Raymond Hettinger96229b12005-03-11 06:49:40 +00001322- Added two new builtins, any() and all().
1323
Brett Cannon409d8f22005-03-05 06:47:57 +00001324- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001325 (e.g., ``class C(): pass`` is no longer a syntax error).
1326 Patch #1176012 added support to the 'parser' module and 'compiler' package
1327 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001328
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001329- Patch #1115086: Support PY_LONGLONG in structmember.
1330
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001331- Bug #1155938: new style classes did not check that __init__() was
1332 returning None.
1333
Tim Petersecc6e6a2005-07-10 22:30:55 +00001334- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001335 ('\') with a specific error message.
1336
Martin v. Löwisff232d72005-03-03 09:24:38 +00001337- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1338
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001339- Bug #1124295: the __name__ attribute of file objects was
1340 inadvertently made inaccessible in restricted mode.
1341
Tim Petersecc6e6a2005-07-10 22:30:55 +00001342- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001343 an ferror() call.
1344
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001345- min() and max() now support key= arguments with the same meaning as in
1346 list.sort().
1347
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001348- The peephole optimizer now performs simple constant folding in expressions:
1349 (2+3) --> (5).
1350
Raymond Hettingera422c342005-01-11 03:03:27 +00001351- set and frozenset objects can now be marshalled. SF #1098985.
1352
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001353- Bug #1077106: Poor argument checking could cause memory corruption
1354 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001355
Jeremy Hyltonab630502005-02-04 18:44:06 +00001356- The parser did not complain about future statements in illegal
1357 positions. It once again reports a syntax error if a future
1358 statement occurs after anything other than a doc string.
1359
Neil Schemenauercf52c072005-08-12 17:34:58 +00001360- Change the %s format specifier for str objects so that it returns a
1361 unicode instance if the argument is not an instance of basestring and
1362 calling __str__ on the argument returns a unicode instance.
1363
Tim Petersf4e69282006-02-27 17:15:31 +00001364- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1365 current thread state when the auto-GIL-state machinery knows about
1366 it (since the thread state is being deleted, continuing to remember it
1367 can't help, but can hurt if another thread happens to get created with
1368 the same thread id).
1369
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001370Extension Modules
1371-----------------
1372

Tim Petersc9d78aa2006-03-26 23:27:58 +00001385 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001386 util, whatsound, whrandom, zmod
1387
1388- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1389
1390- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001391 is deprecated. The undocumented re.engine variable no longer exists.
1392
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001393- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1394 SS2 (single-shift 2) escape sequences correctly.
1395
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001396- The unicodedata module was updated to the 4.1 version of the Unicode
1397 database. The 3.2 version is still available as unicodedata.db_3_2_0
1398 for applications that require this specific version (such as IDNA).
1399
Neal Norwitzb62c4332006-03-04 18:35:47 +00001400- The timing module is no longer built by default. It was deprecated
1401 in PEP 4 in Python 2.0 or earlier.
1402
Guido van Rossum1968ad32006-02-25 22:38:04 +00001403- Patch 1433928: Added a new type, defaultdict, to the collections module.
1404 This uses the new __missing__ hook behavior added to dict (see above).
1405
Georg Brandldbd83392006-02-20 09:42:33 +00001406- Bug #854823: socketmodule now builds on Sun platforms even when
1407 INET_ADDRSTRLEN is not defined.
1408
Georg Brandlf4f44152006-02-18 22:29:33 +00001409- Patch #1393157: os.startfile() now has an optional argument to specify
1410 a "command verb" to invoke on the file.
1411
Neal Norwitz082b2df2006-02-07 07:04:46 +00001412- Bug #876637, prevent stack corruption when socket descriptor

1414
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001415- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1416 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1417 mmap.mmap(0, size) should not be used on Windows for anonymous memory.

1420 than the system default domain.
1421
Martin v. Löwis14694662006-02-03 12:54:16 +00001422- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1423 are reported, the limit on path name lengths is removed, and stat reports
1424 WindowsError now (instead of OSError).
1425
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001426- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

Michael W. Hudson8137bea2005-07-27 20:24:40 +00001500- Patch #1231069: The fcntl.ioctl function now uses the 'I' code for
1501 the request code argument, which results in more C-like behaviour
1502 for large or negative values.
1503
Tim Petersecc6e6a2005-07-10 22:30:55 +00001504- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

1519
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00001520- operator.itemgetter() and operator.attrgetter() now support retrieving

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001544- the cPickle module no longer accepts the deprecated None option in the
1545 args tuple returned by __reduce__().
1546
Raymond Hettingerb2594052004-12-05 09:25:51 +00001547- itertools.islice() now accepts None for the start and step arguments.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001560- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1561 been renamed to have only a single underscore prefix. This was done to
1562 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001563
Nick Coghlan43832302006-04-23 17:04:07 +00001564- PEP 338: new module runpy defines a run_module function to support
1565 executing modules which provide access to source code or a code object
1566 via the PEP 302 import mechanisms.
1567
Anthony Baxter93f5b932006-04-03 08:05:07 +00001568- The email module's parsedate_tz function now sets the daylight savings
1569 flag to -1 (unknown) since it can't tell from the date whether it should

1576 in attribute values.
1577
Anthony Baxterc51ee692006-04-01 00:57:31 +00001578- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001579 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001580 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001581 module will not be built.
1582
Tim Petersc17976e2006-04-01 00:26:53 +00001583- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1584 aren't officially supported here, and trying to use them will probably
1585 raise an exception some day. But dicts have been allowed, and "mostly
1586 worked", so support for them won't go away without warning.
1587
Georg Brandl338ef7d2006-03-31 18:42:16 +00001588- Bug #1445068: getpass.getpass() can now be given an explicit stream
1589 argument to specify where to write the prompt.
1590
Georg Brandl22ec80b2006-03-31 18:25:44 +00001591- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1598
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001599- Queue.Queue objects now support .task_done() and .join() methods
1600 to make it easier to monitor when daemon threads have completed
1601 processing all enqueued tasks. Patch #1455676.
1602
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001603- popen2.Popen objects now preserve the command in a .cmd attribute.

1606
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001607- email 4.0 package now integrated. This is largely the same as the email 3.0
1608 package that was included in Python 2.3, except that PEP 8 module names are
1609 now used (e.g. mail.message instead of email.Message). The MIME classes
1610 have been moved to a subpackage (e.g. email.mime.text instead of
1611 email.MIMEText). The old names are still supported for now. Several
1612 deprecated Message methods have been removed and lots of bugs have been
1613 fixed. More details can be found in the email package documentation.
1614
Walter Dörwald40108c92006-03-27 08:15:44 +00001615- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1616 (a subclass of tuple) that provides incremental decoders and encoders
1617 (a way to use stateful codecs without the stream API). Python functions
1618 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1619 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1620 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001621
Walter Dörwald067db482006-03-15 22:17:27 +00001622- Patch #1359365: Calling next() on a closed StringIO.String object raises
1623 a ValueError instead of a StopIteration now (like file and cString.String do).
1624 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1625 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001626
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001627- A regrtest option -w was added to re-run failed tests in verbose mode.

1637
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001638- PEP 343: new module contextlib.py defines decorator @contextmanager
1639 and helpful context managers nested() and closing().
1640
Martin v. Löwis415ed932006-02-27 19:56:30 +00001641- The compiler package now supports future imports after the module docstring.
1642

1645
Georg Brandlc98eeed2006-02-19 14:57:47 +00001646- Patch #1215184: FileInput now can be given an opening hook which can

Martin v. Löwis3e865952006-01-24 15:51:21 +00001675 specifications, raises IOErrors when proxies for unsupported protocols
1676 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00001699 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1700 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1701 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1702 Ronald L. Rivest offered this advice for Python:
1703
1704 "The consensus of researchers in this area (at least as
1705 expressed at the NIST Hash Function Workshop 10/31/05),
1706 is that SHA-256 is a good choice for the time being, but
1707 that research should continue, and other alternatives may
1708 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001709
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001710- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl532efab2005-08-24 22:34:21 +00001755
Georg Brandlb9256022005-08-24 18:46:39 +00001756- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
1757 ContentTooShortException, when the actually downloaded size does not
1758 match the Content-Length header.
1759
Martin v. Löwis0a5d4a22005-08-24 14:55:22 +00001760- Bug #1121494: distutils.dir_utils.mkpath now accepts Unicode strings.
1761
Martin v. Löwis56066d22005-08-24 07:38:12 +00001762- Bug #1178484: Return complete lines from codec stream readers
1763 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001764 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001765

1779
Georg Brandla4a8b822005-07-15 09:13:21 +00001780- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
1781 parameter, but uses the usual "kwargs=None".
1782
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001783- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00001784 Patch #1209527 (Contributed by Connelly).
1785
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00001786- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
1787 to W3C name (404 -> 'Not Found'). RFE #1216944.
1788
Georg Brandl9e43acf2005-07-04 17:16:07 +00001789- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1790 as this can cause problems with apps closing all file descriptors.
1791
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001792- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001793 it can be missing in embedded interpreters

1801
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001802- The tokenize module now detects and reports indentation errors.
1803 Bug #1224621.
1804
Raymond Hettinger68c04532005-06-10 11:05:19 +00001805- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001806 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001807 the generate_tokens() function now accepts a callable argument that
1808 terminates by raising StopIteration.
1809
Georg Brandl9166e1a2005-06-04 09:20:03 +00001810- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1811
Georg Brandl268e61c2005-06-03 14:28:50 +00001812- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1813 component of the path.
1814
Skip Montanaro174dd222005-05-14 20:54:16 +00001815- Patch #1120353: The xmlrpclib module provides better, more transparent,
1816 support for datetime.{datetime,date,time} objects. With use_datetime set
1817 to True, applications shouldn't have to fiddle with the DateTime wrapper
1818 class at all.
1819
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001820- distutils.commands.upload was added to support uploading distribution
1821 files to PyPI.
1822
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001823- distutils.commands.register now encodes the data as UTF-8 before posting
1824 them to PyPI.
1825
Raymond Hettinger267b8682005-03-27 10:47:39 +00001826- decimal operator and comparison methods now return NotImplemented
1827 instead of raising a TypeError when interacting with other types. This
1828 allows other classes to implement __radd__ style methods and have them
1829 work as expected.
1830
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001831- Bug #1163325: Decimal infinities failed to hash. Attempting to
1832 hash a NaN raised an InvalidOperation instead of a TypeError.
1833
Tim Petersecc6e6a2005-07-10 22:30:55 +00001834- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1868
Guido van Rossumd0641422005-02-03 15:01:24 +00001869- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1870 disables recursive traversal through instance attributes, which can
1871 be exploited in various ways.
1872
Tim Peterse3547fd2005-12-16 23:13:57 +00001873- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001874 flags on the HTTP listening socket.
1875
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001876- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1877 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1878
Fred Drakefbdeaad2006-07-29 16:56:15 +00001879- Patches #893642, #1039083: add allow_none, encoding arguments to
1880 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001881
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001882- Bug #1110478: Revert os.environ.update to do putenv again.
1883
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001884- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1885
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001886- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1887
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001888- Enhancements to the csv module:
1889
1890 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001891 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001892 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001893 + Dialect parameter parsing has been re-implemented to improve error
1894 reporting.
1895 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1896 dictates.
1897 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001898 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001899 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001900 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1901 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001902 + reader now allows \r characters to be quoted (previously it only allowed
1903 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001904 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001905 + Dialect classes passed to the module are no longer instantiated by
1906 the module before being parsed (the former validation scheme required
1907 this, but the mechanism was unreliable).
1908 + The dialect registry now contains instances of the internal
1909 C-coded dialect type, rather than references to python objects.
1910 + the internal c-coded dialect type is now immutable.
1911 + register_dialect now accepts the same keyword dialect specifications
1912 as the reader and writer, allowing the user to register dialects
1913 without first creating a dialect class.
1914 + a configurable limit to the size of parsed fields has been added -
1915 previously, an unmatched quote character could result in the entire
1916 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001917 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001918 the parser field size limit (returning the former limit). The initial
1919 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001920 + A line_num attribute has been added to the reader object, which tracks
1921 the number of lines read from the source iterator. This is not
1922 the same as the number of records returned, as records can span
1923 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001924 + reader and writer objects were not being registered with the cyclic-GC.
1925 This has been fixed.
1926
Brett Cannone6539c42005-01-08 02:43:53 +00001927- _DummyThread objects in the threading module now delete self.__block that is
1928 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1929 lock primitives tend to be limited in number and thus should not be wasted on
1930 a _DummyThread object. Fixes bug #1089632.
1931
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001932- The imghdr module now detects Exif files.
1933
Raymond Hettinger6065d322004-12-20 23:51:53 +00001934- StringIO.truncate() now correctly adjusts the size attribute.
1935 (Bug #951915).
1936
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001937- locale.py now uses an updated locale alias table (built using
1938 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1939 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001940 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001941
Raymond Hettinger3557f422004-12-07 12:02:02 +00001942- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1943
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001944- the pickle module no longer accepts the deprecated None option in the
1945 args tuple returned by __reduce__().
1946
Brett Cannon84667c02004-12-07 03:25:18 +00001947- optparse now optionally imports gettext. This allows its use in setup.py.
1948
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001949- the pickle module no longer uses the deprecated bin parameter.
1950
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001951- the shelve module no longer uses the deprecated binary parameter.
1952
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001953- the pstats module no longer uses the deprecated ignore() method.
1954
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001955- the filecmp module no longer uses the deprecated use_statcache argument.
1956
Raymond Hettinger664347b2004-12-04 21:21:53 +00001957- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1958 extended or overridden by subclasses. Formerly, the subclassed method would
1959 be ignored by the rest of the module. (Bug #1078905).
1960
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001961- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001962 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001963
Walter Dörwald36733692004-12-22 12:50:50 +00001964- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1965 once when a size argument is given. This prevents a buffer overflow in the
1966 tokenizer with very long source lines.
1967
Barry Warsaw538561e2006-01-01 21:48:54 +00001968- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1969 immediately after creating the object, without any intervening
1970 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001971
Skip Montanaro05885812005-01-16 20:48:27 +00001972- The reconvert.quote function can now emit triple-quoted strings. The
1973 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001974
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001975- ``UserString.MutableString`` now supports negative indices in
1976 ``__setitem__`` and ``__delitem__``
1977
Greg Ward40407942005-03-05 02:53:17 +00001978- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1979 correctly.
1980
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001981- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1982 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1983 character even if the user has passed a size parameter to get a proper
1984 line ending. Remove the special handling of a "\r\n" that has been split
1985 between two lines.
1986
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001987- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1988 about illegal code points. The codec now supports PEP 293 style error
1989 handlers.
1990
Walter Dörwald78a78b02005-09-01 12:04:29 +00001991- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001992 from the input stream, so that the output is a byte string in the correct
1993 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001994
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001995- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1996 considering it exactly like a '*'.
1997
Walter Dörwald007f8df2005-10-09 19:42:27 +00001998- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1999 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002000
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002001- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2002
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002003- Patch #1413711: Certain patterns of differences were making difflib
2004 touch the recursion limit.
2005
Walter Dörwald58917a62006-03-31 15:26:22 +00002006- Bug #947906: An object oriented interface has been added to the calendar
2007 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002008 called as a script (e.g. via ``python -mcalendar``). Localized month and
2009 weekday names can be ouput (even if an exotic encoding is used) using
2010 special classes that use unicode.

2019
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002020- Build support for Win64-AMD64 was added.
2021
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002022- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2023
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002024- Patch #881820: look for openpty and forkpty also in libbsd.
2025
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002026- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2027 The zlib module is now builtin on Windows.
2028
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002029- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2030
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002031- Bug #1189330: configure did not correctly determine the necessary
2032 value of LINKCC if python was built with GCC 4.0.
2033
Trent Mick8321b422005-07-26 02:29:21 +00002034- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2035 vulnerability in zlib 1.2.1 and 1.2.2.
2036
Brett Cannon08cd5982005-04-24 22:26:38 +00002037- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2038 flags that change binary compatibility. Changes were also made to
2039 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002040 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002041
Bob Ippolitoed233462005-03-29 13:47:59 +00002042- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2043 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2044 no longer exists). This configure patch makes things right.
2045
Martin v. Löwise2713be2005-03-08 15:03:08 +00002046- Bug #1158607: Build with --disable-unicode again.
2047
Brett Cannon46d96232005-02-16 00:07:19 +00002048- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2049 defined. Discovered as a result of not being able to build on OS X.
2050
Brett Cannon516592f2004-12-07 00:42:59 +00002051- setup.py now uses the directories specified in LDFLAGS using the -L option
2052 and in CPPFLAGS using the -I option for adding library and include
2053 directories, respectively, for compiling extension modules against. This has
2054 led to the core being compiled using the values in CPPFLAGS. It also removes
2055 the need for the special-casing of both DarwinPorts and Fink for darwin since
2056 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2057 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2058 Fink, ``-I/opt/local/include`` for DarwinPorts).
2059
Brett Cannon43802422005-02-10 20:48:03 +00002060- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2061 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2062 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2063 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002065C API
2066-----
2067
Tim Petersc9d78aa2006-03-26 23:27:58 +00002068- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2069 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2070 is obtained via the ``PyObject_`` family, it must be released via the
2071 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2072 always been officially true, but when Python's small-object allocator was
2073 introduced, an attempt was made to cater to a few extension modules
2074 discovered at the time that obtained memory via ``PyObject_New`` but
2075 released it via ``PyMem_DEL``. It's years later, and if such code still
2076 exists it will fail now (probably with segfaults, but calling wrong
2077 low-level memory management functions can yield many symptoms).
2078
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002079- Added a C API for set and frozenset objects.
2080

2082
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002083- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2084 mapping argument now. This string is used as a mapping table. Byte values
2085 greater than the length of the string and 0xFFFE are treated as undefined
2086 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00002092- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002093
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002094- Patch #1276356: New resource "urlfetch" is implemented. This enables
2095 even impatient people to run tests that require remote files.
